Determine the stagnation and static pressure and temperature at the exit of an axial flow expander with the following specifications:
Inlet stagnation temperature, To = 1400K
Inlet stagnation pressure, Po = 10 bars
Mean flow velocity, U = 400m/sec
Exit flow velocity, C = 380m/sec (axial)
Cp = 1200J/kgK
n = 0.9
What is the stagnation to static isentropic and polytropic efficiencies of the expander?
