Argon gas is contained in a cylinder fitted with a frictionless piston. Initially, the cylinder
contains 200 L of Argon at 140 kPa and 10o
C. The gas is then compressed in a polytropic
process according to the relationship Pvn = C until the final pressure and temperature are 700
kPa and 180o
C respectively. For Argon; R = 0.2081 kJ/kg.K and cv = 0.3122 kJ/kg.K.
i) Sketch the system and the details of the process.
ii) Show the process on a P-v diagram
iii) Determine the polytropic exponent, n
iv) Calculate the work involved during the process [kJ]
v) Calculate the heat transfer during this process [kJ]
