Air modeled as an ideal gas enters a steady state adiabatic

Assignment Help Mechanical Engineering

Air (modeled as an ideal gas) enters a steady state adiabatic turbine at 1200 K and exits at 100 kPa, 700 K. The isentropic efficiency is 0.855.

Find:

a. the pressure at the inlet (kPa)

b. the power per unit mass air flowing (kJ/kg)

c. the entropy production rate per unit mass air flowing (kJ/kgK)
