# Water is the working fluid in an ideal Rankine cycle Steam enters the turbine at 1400 lbf in2 and 1000°F The net power output of the cycle

Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 1400 lbf/in2 and 1000°F. The net power output of the cycle is 1 x 10^9 Btu/hr.Cooling water experiences a temperature increase from 60°F to 76°F, with negligible pressure drop, as it passes through the condenser. Plot the following quantitiesversus the condenser pressure ranging from 0.3 lbf/in2 to 14.7 lbf/in^2 (while maintaining a constant net power output):
a) The mass flow rate of steam, in lb/h
b) The rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator
c) The thermal efficiency
d) The mass flow rate of cooling water, in lb/h
e) Discuss the results for each of the curves above
