solution

Steam at 140 lbf/in.2 , 1000 F enters an insulated turbine operating at steady state with a mass flow rate of 3.24 lb/s and exits at 2 lbf/in.2 Kinetic and potential energy effects are negligible.

(a) Determine the maximum theoretical power that can be developed by the turbine, in hp, and the corresponding exit temperature, in F.

(b) If the steam exits the turbine at 200 F, determine the isentropic turbine efficiency

Steam at 5 MPa and 600 C enters an insulated turbine operating at steady state and exits as saturated vapor at 50 kPa. Kinetic and potential energy effects are negligible. Determine

(a) the work developed by the turbine, in kJ per kg of steam flowing through the turbine.

(b) the isentropic turbine efficiency.
