Water is the most common working fluid in a Rankine heat engine, but there is no fundamental reason why a Rankine heat engine couldn’t be designed with other working fluids. Suppose a heat engine is to operate with the following specifications:

∎ Quality (q) of fluid exiting turbine must be at least 0.9.

∎ The fluid leaving the boiler is vapor at T=100°C. Its pressure can be specified as needed to meet the constraint that q > 0.9.

∎ The fluid leaving the condenser is saturated liquid at T = 40°C Turbine efficiency is = 0.8 Find the state of the fluid exiting the turbine, the net work produced by the cycle per kilogram ofoperating fluid, and the efficiency of the cycle for each of the following operating fluids.

A. Water

B. Ammonia (Use Figure 6-2 for data)
