Following data received from particular industry, $0\mathrm{.}5k\frac{g}{s}$ of air enters the heat exchanger at $400$ K $,$ then the air enters an isentropic gas turbine at $1400$ K $,1000$ kPa and leaves at $500$ kPa $.$

Part$-$I:

Determine:

The heat transfer from the heat exchanger,

Temperature of the air at the exit of turbine and

Power output of the turbine.

Assumption:

For Pipe

Length $=10m,$ Pipe Diameter $=0\mathrm{.}2m,$ Roughness $=40m$

Hint:

Use Pipe $($Heat Exchanger$)$ and Simple Turbine.

Give mass source at inlet boundary condition of the heat exchanger.

Part$-$II:

After doing the preliminary simulation analysis with Flownex with the above data, the company expectation is that the power produced by the turbine should be $140$ kW $.$

As a design engineer how will you use Flownex simulation tool to suggest the company a suitable change in value of mass flow rate of turbine only to achieve the required power output of $140$ kW from the turbine.
