Consider a piston cylinder device with a volume of 0.04 m3 and initially contains air at 293 K and 1 bar.
Consider a piston cylinder device with a volume of 0.04 m3 and initially contains air at 293 K and 1 bar. It is desired to reverse the cycle and use it as a refrigerator. In this case the process would begin with PV1.36 = constant process from an initial state of 293 K and a pressure of 10 Bars. The gas is allowed to expand to a volume 3.5 times the volume of state 1. It then follows a...

Uncertainty calculation I want to determine the air density (ρ,
in kg/m3) using the following equation.
p=(1/R)*(P/T)
where
P : barometric pressure, in Pa
T: temperature, in K
R: specific gas constant for dry air, 289.7 J/(kg·K) [assume
constant has no uncertainty]
I performed a sample-to-sample experiment with 6
repetitions/samples (n = 6). I got following results:
P = 96,389 ± 167 Pa
T = 311.8 ± 2.93 K

3.0 kg of air initially occupying a volume of 0.01 m3 at a
pressure of 95.0 bar expands in a piston-cylinder assembly
isothermally and without irreversibilities until the volume is 0.05
m3. Using the Redlich-Kwong equation of state, determine the
1. temperature during the process, in K
2. final pressure, in bar

Ammonia is initially at a temperature of -10° C and a specific
volume of 0.07 m3/kg. The ammonia undergoes an isobaric expansion
to a final specific volume of 0.22 m3/kg. Evaluate the specific
work done on the ammonia in kJ/kg and the specific heat transfer to
the ammonia in kJ/kg. Neglect changes in kinetic energy and
potential energy.

0.5 bar and 300 K. A hole develops in the wall, and air from the
surroundings at 1 bar, 300 K flows in until the pressure in the
tank reaches 1 bar. Heat transfer between the contents of the tank
and the surroundings is negligible. Determine the final temperature
in the tank, in K. What is the entropy generation of the process?
