Question

Steam is the working fluid in an actual Rankine cycle. Steam enters the turbine at 8.0 MPa and 550 deg. C; and saturated liquid exits the condenser at a pressure of 0.008 MPa. The net power output of the cycle is 110 MW. The turbine and the pump each have an isentropic efficiency of 83%

Illustrate and label the TS diagram and determine the cycle

(a) the cycle thermal efficiency

(b) the back work ratio

(c)the mass flow rate of the steam, in kg/h,

(d) the rate of heat transfer into the working fluid as it passes through the boiler, in MW,

(e) the rate of heat transfer, from the condensing steam, as it passes through the condenser, in MW,

(f) the mass flow rate of the condenser cooling water, in kg/hr., if cooling water enters the condenser at 15 deg. C and exits at 35 deg. C.
