Water is the working fluid in an ideal Rankine cycle. Su- perheated vapor enters the turbine at 8 MPa, 480C. The con- denser pressure is 8 kPa. The net power output of the cycle is 100 MW. Determine for the cycle (a) the rate of heat transfer to the working fluid passing through the steam generator, in kW. (b) the thermal efficiency. (c) the mass flow rate of condenser cooling water, in kg/h, if the cooling water enters the condenser at 15C and exits at 35C with negligible pressure change.

Question
Water is the working fluid in an ideal Rankine cycle. Su-
perheated vapor enters the turbine at 8 MPa, 480C. The con-
denser pressure is 8 kPa. The net power output of the cycle is
100 MW. Determine for the cycle
(a) the rate of heat transfer to the working fluid passing
through the steam generator, in kW.
(b) the thermal efficiency.
(c) the mass flow rate of condenser cooling water, in kg/h, if
the cooling water enters the condenser at 15C and exits
at 35C with negligible pressure change.
