Water is the working fluid in an ideal Rankine cycle. Superheated vapor enters the turbine at 8 MPa, 480°C. The condenser 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 15°C and exits at 35°C with negligible pressure change.

Question
Transcribed Image Text:Water is the working fluid in an ideal Rankine
cycle. Superheated vapor enters the turbine at 8
MPa, 480°C. The condenser 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 15°C and exits at 35°C with
negligible pressure change.
