Document Summary

Hume, scottish empiricist and skeptic, is one of the most influential figures in the history of modern philosophy. Like locke and berkeley, hume maintained that any factual knowledge that we have is acquired through experience. By the eighteenth century, the term idea was used so broadly that hume made a clear distinction between impressions and ideas. By impressions hume refers to what we might call sense impressions. By ideas hume refers to images in the mind. If i see a green tree, i have an impression of green. If i close my eyes and imagine what i saw, i have an idea of green. Hume regards ideas as weak copies of impressions. All our ideas can be traced back ultimately to impressions. Hume maintains that in order for a term (such as a word) to have meaning it must be possible to specify from what impression the supposed idea is derived.

Which of the following is an accurate statement?
A. An important distinction between the Diesel cycle and the Ottocycle is that there is no fuel in the cylinder at the beginning ofthe compression stroke and no spark plug is used.
B. An important distinction between the Diesel cycle and the Ottocycle is that for the Diesel cycle high efficiencies may beobtained with low compression ratios.
C. Because a Diesel engine requires no fuel ignition system, Dieselengines tend to be lighter and easier to start than a comparablegasoline engine.
D. The efficiency of the Otto cycle does not depend on thecompression ratio.
E. A typical gasoline engine has an efficiency of about 2%.

When air is compressed its temperature increases. The compression process can be done in multiple stages with cooling between thestages. This reduces the amount of work required in the compression process.

The two stage compressor shown in the figure below takes in air at room condition(300 K and 100 kPa) and compresses it to 2 MPa. The cooler then cools the air to 340 K, after which it enters the second stage, which has an exit pressure of 15MPa.

Both compression stages are adiabatic and reversble.

(a) Find the specific heat transfer in the intercooler( the amount of heat in kJ/kg that must be removed from the air).

(b) Determine the total specific work.

(c) Compare this to the work required with no intercooler.

Suppose you listen to a 440 Hz sound wave, which travels throughthe air with speed 344 m/s. How many compressions per second entereach of your ears?


A) 1/344

B) 344

C) 1/440

D) 440
