Unformatted text preview: p = 1.0035 kJ/kgK and c v = 0.7165 kJ/kgK are constants, and that R = 0.287 kJ/kgK. a) For each leg of the cycle identify whether the heat added to the system, Q, and the work done by the system, W, are positive, negative or zero. b) For each leg of the cycle calculate the work and heat transfer, the change in internal energy and the change in enthalpy. c) What is the net work of the cycle? d) What is the thermal efficiency of the cycle? e) If you reversed the direction of the cycle and used it as a refrigerator, what is the maximum amount of heat you could you remove per Joule of power input?
