$26\%)$ The steady power output from an adiabatic steam turbine is the input power to a water mp with the conditions shown below. The pump has an isentropic efficiency of $90\%.$ The inlet water nperature to the pump is $25C.$ The mass flow rate of water to the pump is $80k\frac{g}{s}$ and the mass flow of steam to the turbine is $2k\frac{g}{s}.$ Other conditions are as shown.
