Example 6: Pater &ber Reavior! Tra Water Pampa Ve=1m WT TR=200 Value A cylinder fitted with a spring-loaded massless piston serves as the supply of steam for a steam turbine. Initially, the cylinder pressure a 2 MPa and the volume is 1 m. The force exerted by the spring is reep at zero-cylinder volume, and the top of the piston is open to the ambient. The cylinder temperature is maintained at a constant 300C by heat transfer from a source at that temperature. A pressure regulator between the cylinder and the turbine maintains a steady 500 kPa, 300C at the turbine inlet, such that when the cylinder pressure drops to 500 kPa, the process stops. The turbine process is reversible and adiabatic, and the exhaust is to a condenser at 50 kPa. Find (a) The turbine work output, (b) Total heat transfer to the cylinder, (c) Total entropy production during this process R Answer: 125.29 kl: 1231.8; 3.648/
