2. Steam enters the turbine as 100% saturated vapour at pressure of 6 MPa, and

saturated liquid enters the pump at a pressure of 0.01 MPa. The net power output of

the cycle is 50 MW. Determine

(i) The thermal efficiency

(ii) The mass flow rate of the system

(iii) The rate of heat transfer into the boiler

(iv) The mass flow rate of the cooling water from the condenser (in kg/s)

The cooling water enters at 20 °C and exits at 40 °C.

 

Please any one help me in this problem...how can i get workdone from power...

because every time i get workdone from enthalpy its unit would be KJ/KG..

 

so how can i get transfer to the workdone..???
