Africtionless piston-cylinder device contains 4.5 kg of nitrogen at 110 kpa and 200 k. nitrogen is now compressed slowly according to the relation pv1.5 = constant until it reaches a final temperature of 360 k. calculate the work input during the process, in kj.

427.392 kJ

Explanation:

m = Mass of gas = 4.5 kg

Initial temperature = 200 K

Final temperature = 360 K

R = Mass specific gas constant = 296.8 J/kgK

= Specific heat ratio = 1.5

Work done for a polytropic process is given by

The work input during the process is -427.392 kJ
