A gas undergoes a process from state 1, where
p1 = 60 lbf/in.2,
v1 = 6.0 ft3/lb, to state 2 where
p2 = 99.6 lbf/in.2, according to
pv1.3 = constant. The relationship
between pressure, specific volume, and internal energy is
u = (0.2651)pv - 95.436
where p is in lbf/in.2, v is in
ft3/lb, and u is in Btu/lb. The mass of gas is
10 lb. Neglecting kinetic and potential energy effects, determine
the heat transfer, in Btu.

A closed piston-cylinder system undergoes a cycle:
Process 1 to 2 is an expansion process where heat is added. The
temperature remains constant.
Process 2 to 3 is a constant volume heat addition process.
Process 3 to 4 is a compression process where heat is lost. The
pressure remains constant.
Process 4 to 1 is polytropic expansion, Pvn=constant
with n=1.4 and it is adiabatic (Q=0).
Assume air, ideal gas, with constant specific heats, k=1.4.
R=.287kJ/kgK
State 1: T=300K, P=150kPa

Air undergoes a polytropic process in a piston–cylinder assembly
from p1 = 1 bar, T1 = 295 K to p2 = 7 bar. The air is modeled as an
ideal gas and kinetic and potential energy effects are negligible.

transfer, each in kJ per kg of air, (1) assuming constant cv
evaluated at 300 K. (2) assuming variable specific heats.

(a)Air, which can be assumed to behave as an ideal gas,
undergoes a process from 150kPa and 400K to 600kPa and 500K within
a piston cylinder. Can this process occur adiabatically? (Think
about what the limitations on ???? are to answer this question).
(b)Now consider air which is compressed in an air compressor
adiabatically from 150kPa and 400K to 1000K and 600kPa. It enters
the air compressor with a mass flow rate of 1kg/s. Determine the
