(30 points) A magic substance (identical phase change temperatures to water, but having difference thermodynamic properties) contained in a piston-cylinder assembly undergoes two processes in series from an initial state where the pressure is 10 bar and the temperature is 400 C. In Process 1-2, the substance is cooled as it is compressed at a constant pressure of 10 bar to the saturated vapor state. In Process 2-3, the substance is cooled further at constant volume to 150 °C. a....

3. (40 pts) A steam power plant based on the Rankine cycle, shown in the below, operates to develop net cycle power. Saturated vapor at 8 bar enters the turbine where it expands to the condenser pressure of 1 bar. Water liquid exits the condenser 30 °C and 1 bar and it is pumped to the boiler pressure of 8 bar. Isentropic efficiencies of the turbine and pump are 80% and 60%. Assume kinetic and potential energies are negligible at...

Problem 3 (50%) The process below is part of a larger steam power plant. Steam in stream 1 enters the turbine at 600 °C, 50 bar with mass flow rate kg/s and exits at 7 bar, 350 °C. Stream 3, which is saturated liquid and is throttled to 2 bar (stream 4). Stream 5 is at 200°C, 2 bar, and is mixed adiabatically with stream 4 in the tank. Stream 6 is wet steam that contains 8% liquid. This stream...

1. (42 points) A piston-cylinder device contains 6 kg of steam at 100°C with a quality of 50 percent. This steam undergoes two processes as follows: 1-2 Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor. 2-3 The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. (a) (24 points) Fill in the table using the given and determined properties. You...
