Q2. The ratio of compression of an engine working on the constant volume cycle is 9.3:1. At the beginning of compression the temperature is 32℃ and at the end of heat supply the temperature is 1205℃

Determine EACH of the following:

a) the temperature at the end of compression and expansion (4)

b) the specific net work and thermal efficiency (6)

c) IF V₁ = 0.1 m³ AND P₁ = 1 bar find the volume and pressure at each point in the cycle (6)

Note: For air γ = 1.4, c_v = 0.718 kJ/kgK
