Arigidtankofvolume0.5m3isconnectedtoapiston–cylinderassemblybyavalve,asshown below. Both vessels contain pure water. They are immersed in a constant-temperature bath at 200oC and 600 kPa. Consider the tank and the piston–cylinder assembly as the system and the constant temperature bath as the surroundings. Initially the valve is closed and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with a quality of 95% (i.e., 95% of the mass of water is vapor). The piston–cylinder assembly initially has a volume...
In the friction-free piston-cylinder assembly, initially there is a volume of 0.1 m³ air at 300 K temperature. The air is heated at a constant pressure of 300 kPa, at a constant piston velocity and a temperature of 600 K for 30 s. In this context, calculate the power to be given to the piston as [kW]. Show the process in the diagram T (° C) - v (m³ / kg).

Consider the piston/cylinder arrangement shown in Fig1. A frictionless piston is free to move between two sets of stops. When 3 the piston rests on the lower stops, the enclosed volume is 0.5 m3. When the piston reaches the upper stops, the volume is 0.8 m . The cylinder initially contains water at 200 kPa, 60% quality. The mass of the piston requires 600 kPa pressure to move it against the outside ambient pressure. a) When heat is transferred until...
1 A piston-cylinder device initially contain 0.4 m3 of 1.8- kg saturated liquid water and steam mixture at 110 kPa. A electric heater in the device is turned on and passes a current of 1.7 A from a 120-V source. Only transfer of electrical work and boundary work exist. The piston initially rests on a set of stops, and a pressure of 200 kPa is required to move the piston. Afterwards the system continues to raise the piston and eventually...
