If the maximum pressure in the cylinder is constrained to 100bar, calculate the temperature at state 3a in [K], and the energy released by the fuel during the C-V combustion process (2 – 3a) in [kJ]. ( T3a = 1970.8 K, Q2-3a = 1.102 kJ)

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
