Question

air is expend reversibility and adiabatically in turbine from 3.5 bar and 26o degree to 1 bar. the turbine is insulated and the inlet velocity is negligible.the exit velocity is 150m/s .find the work output of the turbine per unit mass of air flow? Cp=1.005kj/kgk,r=1.4

Answer 1

Answer:

Air is expanded reversibly and adiabatically in a turbine from 3.5 bar and 260 ℃ to 1 bar. The turbine

is insulated and the inlet velocity is negligible. The exit velocity is 150 m/s. Find the work output of the

turbine per unit mass of air flow. Take for air, Cp = 1.005 kJ/kg K, and = 1.4
