Consider a steam power plant that operates on a simple nonideal Rankine cycle and has a net power output of 38 MW. Steam enters the turbine at 7MPa and 500C and is cooled in the condenser at a pressure of 10 kPa by running cooling water from a lake through the tubes of the condenser at a rate of 1550 kg/s. if the efficiencies of the pump and compressor are both 87%, determine
a) the thermal efficiency of the cycle
b) the mass flow rate of steam
c) the temperature rise of the cooling water dont know how to solve (c)
