Question: A newly developed compound is being considered for use as the working fluid in a small Rankine-cycle power plant driven by a supply of waste

A newly developed compound is being considered for use as the working fluid in a small Rankine-cycle power plant driven by a supply of waste heat. Assume the cycle is ideal, with saturated vapor at 200°C entering the turbine and saturated liquid at 20°C exiting the condenser. The only properties known for this compound are molecular weight of 80 kg/kmol, ideal gas heat capacity CPO= 0.80 kJ/kg K and TC = 500 K, PC = 5 MPa. Calculate the work input, per kilogram, to the pump and the cycle thermal efficiency.
