Document Summary
Me 235 thermodynamics i / winter 2014 / section 002. 2. 74 air in an internal combustion engine has 227oc, 1000 kpa with a volume of 0. 1 m3. Now combustion heats it to 1800 k in a constant volume process. 2. 85 find the compressibility factor (z) for saturated vapor ammonia at 100 kpa and at 2000 kpa. Show the possible process in a p-v diagram. 3. 33 a hydraulic hoist raises a 1750 kg car 1. 8 m in an auto repair shop. The hydraulic pump has a constant pressure of 800 kpa on its piston. 3. 46 the r-410a in problem 3. 14 c is at 1000 kpa, 50oc with mass 0. 1 kg. It is cooled so the volume is reduced to half the initial volume. The piston mass and gravitation is such that a pressure of 400 kpa will float the piston. 3. 47 a 400-l tank a, see figure p3. 47, contains argon gas at 250 kpa, 30 oc.
