40 ft3 of air at 14.7 psia is compressed
isentropically at 30°C. If the volume is
reduced to 3 ft3,what is the final pressure
in psia?
Use k = 1.4 for air.
16 kgm of a gas undergoes a polytropic
process with pv129 C. During the
process, the temperature changed from
33 °C to 270 °C. It the initial volume is
1.359 liters, find the final volume in cubic
meter?
