A mass of 5.5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 101.325 kPa. Initially, 2.3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 21 percent. Determine: a) the initial...

1.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 277°C from a pressure of 5.1 bar to a pressure of 2.7 bar. Evaluate the work, in kJ/kg. 2.Nitrogen (N2) contained in a piston–cylinder arrangement, initially at 9.3 bar and 437 K, undergoes an expansion to a final temperature of 300 K, during which the pressure–volume relationship is pV1.1 = constant. Assuming the ideal gas model for the N2, determine the heat transfer in kJ/kg. 3.Argon contained in...

A rigid tank having a volume of 0.1 m3 initially contains water as a two-phase liquid-vapor mixture at 1 bar and a quality of 1%. The water is heated in two stages: Stage 1: Constant-volume heating until the pressure is 20 bar. (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar. (Note: Use transient analysis with all the water leaving having a quality of...

(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....
