Q1. In a non-flow process 0.4 m³ of a gas is initially compressed from 3 bar and 250℃ to 25 bar and 0.2 m³ according to the law PVⁿ = C. Then the volume of the gas is reduced isothermally to 0.09 m³

Calculate EACH of the following:

a) the temperature after the initial compression (2)

b) the final pressure (2)

c) the specific work done in the initial compression (2)

d) the total specific heat transfer (6)

e) sketch the process on p-V and T-s graphs. (4)

Note: γ = 1.32, n = 3.06, c₀ = .2058 4 J/kgK c_v = 15,59.4 J/kgK
