A system consists of 2 kg of carbon dioxide gas initially at
state 1, where p1 = 1 bar,
T1 = 300 K. The system undergoes a power cycle
consisting of the following processes:
Process 1–2: Constant volume to p2 = 2
bar.
Process 2–3: Expansion with pv1.4 =
constant.
Process 3–1: Constant-pressure compression.
Assuming the ideal gas model and neglecting kinetic and potential
energy effects, calculate thermal efficiency.

A system consists of 2 kg of carbon dioxide gas initially at
state 1, where p1 = 1 bar,
T1 = 300 K. The system undergoes a power cycle
consisting of the following processes:
Process 1–2: Constant volume to p2 = 4
bar.
Process 2–3: Expansion with pv1.4 =
constant.
Process 3–1: Constant-pressure compression.
Assuming the ideal gas model and neglecting kinetic and potential
energy effects, calculate thermal efficiency.

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.

According to the ideal gas law, a 1.041 mol
sample of carbon dioxide gas in a
1.016 L container at 270.0 K
should exert a pressure of 22.70 atm. By what
percent does the pressure calculated using the van der Waals'
equation differ from the ideal pressure? For
CO2 gas, a = 3.592
L2atm/mol2 and b =
4.267×10-2 L/mol.
%
Hint: % difference = 100×(P ideal - Pvan
der Waals) / P ideal
