A geothermal energy source is to be used in the operation of a Rankine power cycle using R134a as the working fluid. The R134a is to leave the heater at 60 psia and 200°F and the ideal turbine at 2 psia. Sketch a T- s diagram. For a mass flow rate of 5 lbm/s, calculate:
i) The maximum power to be produced by the turbine
ii) The heat loss in the condenser
iii) The pump horsepower required
iv) The rate of heat addition to the R134a
v) The efficiency of the ideal cycle
