Problem $11\mathrm{.}083-$ Combined gas$-$steam power plant

The gas$-$turbine portion of a combined gas$-$steam power plant has a pressure ratio of $16.$ Air enters the

compressor at $300$ K at a rate of $11\mathrm{.}00k\frac{g}{s}$ and is heated to $1500$ K in the combustion chamber. The

combustion gases leaving the gas turbine are used to heat the steam to $400C$ at $10$ MPa in a heat

exchanger. The combustion gases leave the heat exchanger at $420$ K $.$ The steam leaving the turbine is

condensed at $15$ kPa $.$ Assume all the compression and expansion processes to be isentropic$.$ For air,

assume constant specific heats at room temperature.

Problem $11\mathrm{.}083.$b $-$ Net power output of the plant

Determine the net power output. $($You must provide an answer before moving on to the next part.$)$

The net power output is

kW$.$
