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.
A piston/cylinder arrangement contains water of quality x = 0.7 in the initial volume of 0.1 m3, where the piston applies a constant pressure of 200 kPa. The system is now heated to a final temperature of 200°C. Determine the work and the heat tr..
