Question

A mass of gas is compressed in a quasi-static process from 80 kPa, 0.1 cubic metre

to 0.4 MPa, 0.03 cubic metre. Assuming that the pressure and volume are related

by pVn = constant, find the direction and magnitude of work transfer.​

Answer 1

Explanation:

Given initial pressure( ) 1 p = 80kPa

Initial volume ( ) 1 V = 0.1 m3]

Final pressure (p2 ) = 0.4 MPa = 400 kPa Final volume (V2 ) = 0.03 m3

As p-V relation pV^n = C

n ln(v1/v2)=ln(p1/p2)

n ?

1.34

Answer 2

Explanation:

Isothermal & adiabatic
