  6. Performance parameter • Thermal efficiency • Bwr, back work ratio

  7. Contohsoal Steam is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 8.0 MPa and saturated liquid exits the condenser at a pressure of 0.008 MPa. The net power output of the cycle is 100 MW. Determine for the cycle • The thermal efficiency, • the back work ratio, • the mass flow rate of the steam, in kg/h, • the rate of heat transfer, , into the working fluid as it passes through the boiler, in MW, • the rate of heat transfer, from the condensing steam as it passes through the condenser, in MW, • the mass flow rate of the condenser cooling water, in kg/ h, if cooling water enters the condenser at 15C and exits at 35C.
