EAS110Y1 : EAS110 homework workbook Answer Keys L10.pdf

I'm working on a project I need some help with (BTW I asked my teacher and I am allowed to ask for help). If there was anything I wasn't clear on please tell me because I'm just hopelessly lost on this. Also just to note this actually has a fair bit of chemistry in it but because it's all related to electricity and there is no chemistal engineering subject Tab I put it here.

Okay so in this project we have a hypothetical scenario. In this scenario I'm on an abandoned island and I need to power a satellite for 97 minutes at 12 volts at 30 amps and 5 volts at 45 amps. But on this island are various supplies including a 1987 V8 engine which I think will provide 12 volts at 30 amps. Now what I need is fuel to get it going. I have 4 deep friers full of oil, 3 cases of magnum bottles of champagne, salt water from the ocean, 21 2 gallon jars of pickled eggs, and 33-5 gallon containers of italian salad dressing, and 23 #10 cans of tomato sauce. There is also an abandoned moonshine still. So using the oil from the friers, the champagne, and getting the oil out of the salad dressing I should be able to get a decent amount of biofuel correct? I also have 9 full 20# propane tanks and I read that propane can be used to make fuel burn more efficiently by taking the place of the air injection. If there anything else from this list that I could make into fuel of some kind? What about Moonshine everything I read mentions sugar and yeast which I don't think I have either of.

So assuming I have that all worked out okay that gets me my 12 volts at 30 amps. But I still need the 5 volts at 45 amps. And one solution I was thinking of was making voltic cells. Amoung the materials I have to work with that are of use here are some 1/2'' and 3/4'' copper pipes, 8 roles of aluminum foil, 23 20ft lengths of 6 in. sch. 40 PVC pipe, 17 20ft lengths of 4in. sch. 40 PVC pipe, and 9 20ft lengths of 2 in. Sch. 40 PVC pipe. I also have some cans of cold galvanizing spray paint ( meaning I have zinc), and various containers including a lot of PVC pipe, 55 gallon plastic drums, and a complete set of commercial pots and pans. I also have various wires but I'll put that asside for now. I also have access to some PH adjust (down)

Now what I want to do is make a battery set up that can deliver 5 volts at 45 amps for 97 minutes.

I know I can make several battery cells and connect them in series and parallel to get the desires voltage and current. But i'm having trouble figuring out what my voltage and amperage would be for each cell. Also how long would the charge last?

I read something called aluminum-air batteries but I'm not clear on how they are made or if they are ideal for what I need. Would using the pickling solution from the pickled eggs as my electrolyte be better than using the salt water? Or should I separate the vinegar out of the salad dressing and us that? Would using the PH adjust (down) help?

I tried looking up some reduction charts but those were all in aqueous. What I was able to get was that for copper and aluminum it was about 2 v potential and for copper Zinc it was about 1.01 v. Is this correct? For a base line lets say I just use the PVC pips, copper pipe, aluminum foil, Salt water, and for wiring I use copper wire. if I"m correct and I get about 2 V from each battery how do I find my amperage? What part of all this affects the current and how would I calculate it? Would using a different kind of wire be better? I have access to a couple different kinds.

As you may recall in the work of Triplett (1898), the presence of others in a bicycle race was found to enhance individual performance. This is called social facilitation (Williams, Harkins, & Karau, 2007). At times, however, the presence of others can detract from individual performance, which is termed social inhibition (Crisp & Turner, 2007). Similarly, social loafing can occur when an individual’s performance within a group decreases due to his or her reliance on others in the group (Crisp & Turner, 2007).

For this Discussion, review the media program, Week 5: The Virtual Office. Focus on the characters in the media and determine which characters displayed social facilitation, social inhibition, and social loafing.

With these thoughts in mind:

Post by Day 3 a description of the characters in the media program demonstrating social loafing, social inhibition, and social facilitation. Explain how you identified them. Then, select one of the characters and, using the current literature, explain two ways you might mitigate their behavior.

Media Program

(Onscreen Text: The employees at the United Cardboard Company often work individually on projects, but as with most environments, they are occasionally asked to participate in group projects. One such group is about to meet right now to plan a presentation for the Board of Directors. Observe the conversation and reactions of various group members to determine which group members exhibit signs of the following: Social Loafing, Social Inhibition, and Social Facilitation.)

(Interior of an office. Ken stands at the front of the conference room.)

KEN: OK, I guess we might as well all get started. As we all know, the big man has requested the five of us to get together and write and conceptualize a presentation to the board on our new packaging system. Maybe we can start by going around and throwing out some initial ideas.

KATHY: Sounds good to me. I think a PowerPoint presentation would do the job well.

GAVIN: I agree. We could follow it up with a physical demonstration of how the packaging looks and folds-- maybe a video of the larger pieces that won't fit into the boardroom.

KEN: Sounds perfect to me. Amanda, Brian, what do you guys think?

BRIAN: Yeah, what you guys said sounds fine.

(Amanda thinks, “I don’t know what to say!”)

KEN: Amanda?

AMANDA: I don't know. I didn't really get much chance to think about this. We only found out we needed to do this together three days ago.

KEN: OK, no worries. Let's focus on the PowerPoint idea. I've been doing a lot of them lately, so I'm happy to take the lead on the design aspect. What do you guys think we should all incorporate into the slides?

GAVIN: I think we should start with where we got the idea for this new packaging -- the company that designed it and the different sizes that it comes in.

KATHY: We should follow that with a graph comparing the old prices to the new ones to illustrate how much we'll be saving over time. Amanda, didn't you have most of that information collected at some point?

(Amanda thinks, “Oh no! What if I deleted that?)

AMANDA: I don't know, maybe, it's been so long. I didn't think I'd need it again for a group project like this.

(Gavin thinks, “I wonder what’s gotten into her. She’s not usually this tense.”)

KEN: That's OK, Amanda, I'm sure we can easily dig it up again. Brian, do you have any other ideas for the PowerPoint slides?

BRIAN: Nah, I think what you guys mentioned sounds right.

(Kathy thinks, “Wow. Way to contribute Brian.”)

KEN: OK then, Kathy and Gavin why don't you send me all of the info and I'll write it up and make the slides. Amanda, don't worry about the cost saving document, I'm sure I can dig it up from my old emails and put it into that slide too.

AMANDA: Are you sure? I'm happy to look. I mean I'm sure I have it somewhere. (Kathy thinks, “She really needs to get it together. Why is she so nervous?”) At least I think I have it somewhere. You won't tell the Board of Directors if I lost it, will you?

KEN: Of course not, we're in it together. So as I was saying, I'll write up and prepare all the PowerPoint slides. Then we can start our presentation with reading and explaining each slide. Then, what?

KATHY: Well, and then I think we should show them the packaging live, and the quick deconstructing techniques.

KEN: Great idea. You and Amanda can demonstrate the folding, while I narrate what you're doing.

(Amanda thinks, “Is he doing too much of the work? And what if I drop everything while he’s talking?”)

GAVIN: And after you all demonstrate the smaller packaging, we could show a quick video of how the really big ones function down at the warehouse. Brian, would you be able to go film that quickly one of these days?

BRIAN: I don't really have any experience with video cameras or anything like that, so...

(Gavin thinks, “I should have seen that one coming.”)

KEN: That's OK. My wife actually just got me this great little camera for our anniversary. It takes great videos. So I can just run down to the warehouse, get some footage, then put it together on this new editing software I just downloaded. Maybe add a little music. It's going to be really slick!

KATHY: Are you sure, I wouldn't mind doing that too.

KEN: Oh no, it's fine. I love this kind of stuff; just leave it to me. But I suppose that's enough planning. Now it's time to get to work and make the presentation a knock out. Go team!

Robatelli's Pizzeria Case StudyIntroduction On the morning of October 31st, Elaine Black, Chief Information Officer at Robatelli's Pizzeria, was waiting for both Jim Saxton, database administrator, and Peter Greyton, operations manager, to come to her office for a meeting. While waiting, Elaine was thinking about the surge of telephone and Internet orders expected to be received through the company's customer order center within the next 12 hours. Halloween had always been the most popular day of the year for people in the greater Pittsburgh area to order pizza from Robatelli's. There were 53 restaurant locations to serve these customers, but only one location to receive all of the orders and forward them to the right restaurant. Elaine's thoughts were interrupted as Jim and Peter entered her office. The following conversation took place: ELAINE Well, guys, it's here again, our biggest day of the year. Not only is Halloween a busy day, but we have the upcoming day after Thanksgiving, the week before Christmas, and Super Bowl Sunday. Can our current computer system's infrastructure and people keep pace with the orders we expect? JIM I think our systems are all running at peak performance. We shouldn't have any computer concerns for today or those other busy days. PETER Everyone in the customer order center is focused on making sure that our customers get their pizzas as ordered. We have plenty of people scheduled to work tonight, so we're good to go. ELAINE Terrific. But every time we face one of these peak sales days, I start wondering about the long-term capacity and effectiveness of our computer systems. Jim, we need to think long term about our computer system. I was just reading an article that I'd like you to take a look at. It's about Anheuser-Busch Companies and their use of data mining. JIM I do agree with you, Elaine; we should always be thinking about how newer IT systems can help us. Could you e-mail me the link to the article? ELAINE Sure, and I would like you to think about how we might use the same approach in our business. Peter, your order center people are doing a great job, but again there's something I'd like us to think about in the long run. As you know, we now have to manually enter all customer order center sales and store sales into our general ledger (GL). I think we could improve a lot of things if those sales are automatically fed into our GL software. Why don't you think about any advantages you see for an automatic interface, and we'll look at the costs compared to those advantages. How's that sound? PETER I'll do that. I'll give it some thought and work on a report about an automatic interface between our GL software and the point of sale systems in our restaurants as well as the phone and Internet sales. How soon do you want to meet again to look at these issues? ELAINE Let's say, in two weeks at the same time. As Jim and Peter left her office, Elaine continued to think about the features of the company's accounting information systems and whether or not data extracted from these systems could facilitate the multiple needs of the company. The focus had always been on providing accurate financial accounting information from the various locations; however, the company's aggressive growth strategies meant increased emphasis on the system's ability to analyze detailed customer information that could be translated into increased sales opportunities. Elaine knew the challenges they faced could very well affect the company's ability to maintain its competitive advantage. She realized that her department must continually improve the company's information systems to help it achieve growth strategies. Operating state-of-the-art systems was imperative to position the company to execute those growth plans. However, she was concerned about the possibility that restrictions of the current information systems could actually prevent the company from doing what it wanted to do. Allowing restrictive systems to prevent them from achieving business strategies was a risk that Elaine would not tolerate!
