A steam power plant operates on an ideal Rankine cycle with two stages of reheat and has a net power output of 60 MW. Steam enters all three stages of the turbine at 550°C. The maximum pressure in the cycle is 10 MPa, and the mini­mum pressure is 30 kPa. Steam is reheated at 4 MPa the first time and at 2 MPa the second time.

Determine

(a) the thermal efficiency of the cycle,
(b) the mass flow rate of the steam.
