Question
3.4 Air is contained in a cylinder fitted with a frictionless. Initially, the cylinder contains 200
Lof air at 300 kPa and 100°C. The air is then compressed in a polytropic process according to
the relationship PV= C until the final pressure and temperature reached 700 kPa and 180°C
respectively. Based on the following information,
a) Determine the mass of the air.
b) Determine the volume of the compressed air.
c) Determine the polytropic exponent, n.
d) Calculate the work involved during the process in kJ.
e) Calculate the heat transferred during the process in kJ.
f) Sketch and label on the P-v diagram of the process.
