Question $4$

A gas turbine power system operates between the pressure of $100$ and $1600$ kPa $.$ The

working fluid is Argon which flows at a rate of $900\frac{m^3}{m}in$ in a Brayton cycle. Argon, with

constant specific heats of $c_v=0\mathrm{.}821k\frac{J}{k}g*K,c_p=1\mathrm{.}108k\frac{J}{k}g*K,$ and $k=1\mathrm{.}35,$

enters the compressor at $40C$ and leaves the turbine at $650C.$ Assume a compressor

isentropic efficiency of $85\%$ and a turbine isentropic efficiency of $88\%.$

Complete the following:

A$.$ Determine the net power output.

B$.$ Show the T$-$s diagram.
