Question

Use cold-air-standard analysis with the fluid modeled as an ideal gas with R=0.287 kJ/kg-K and constant k=1.4. Neglect changes in kinetic and potential energy. Consider a SSSF of air at 300 K and 100 kPa entering the compressor of a Simple Brayton Cycle Gas Turbine powerplant. The cycle pressure ratio is 40 and maximum cycle temperature is 1800 K. For compressor isentropic efficiency of 82% the compressor work input per unit mass = __ kJ/kg (enter the nearest positive integer value)

Answer 1

note: by mistake, I have not put a negative sign before 1500, so please you can put negative sigh before 1500. then the solution becomes finally positive in results.

I hope you can understand the solution.

Thank you!!!
