STEP 2
Your first customer asked for an air piston-cylinder to use it in air compressors for
generating high pressure. Your role in your company is to analyze, describe the
operation of the system and their properties, explain and demonstrate the
application of the first law of themodynamics to this system, as well as, illustrate
the importance of expressions for work done in the system through the
application of the first law.
Describe the operation of the themodynamic system in Figure 1 and its properties, by
constructing a P-V and T-V plots showing the process, the path, and the states then show
the work under the curve on the P-V plot.
STEP 3
Explain the application of the first law of thermodynamics to the system and explain the
system parameters in terms of energy forms changes using the non-flow energy equation
(NFEE) for the system and how they affect other parameters such as the final air
temperature, by stating the appropriate assumptions and writing the general formula and
then deducing a final short form of first law for the system under study.

STEP 4
If the shaft rotates 200 revolution and the added heat is 500 kJ. Find the expressions for
work done by the shaft and calculate the value of applied torque on the shaft.

The required piston-cylinder device is frictionless and initially contains 3 kg of
air at 150 kPa in 0.2 m³. The air is now heated by using a fire. Also, a
mechanical shaft is rotating. Then the piston starts touching the spring when the
