Consider a turbine; working substance is air.
Cp = 1.0 kJ/kgK , k=1.4 ,V1=0.03 m3/kg , V2=0.08 , P1 = 2.5 bar
; state 1 is enterance, state 2 is the exit of the turbine. The turbine is not ideal (isentropic); the air goes through a state change according to
PV^n = constant , n =1.6
Compute the ideal and actual specific works and turbine efficiency.

13)  A turbine, operating under steady-flow conditions, receives 5000 kg of steam per hour. The steam enters the turbine at a velocity of 3000 m/min, an elevation of 5 m and a specific enthalpy of 2787 kJ/kg. It leaves the turbine at a velocity of 6000 m/min, an elevation of 1 m and a specific enthalpy of 2259 kJ/kg. Heat losses from the turbine to the surroundings amount to 16736 kJ/h. Determine the power output of the turbine. 14) 12 kg...
