Question 1 A piston-cylinder assembly contains 3.2 kg of water at 211.9oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 51.5 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 230 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water. Question 2 Water, initially saturated vapor at 10.2 bar, fills...

A piston cylinder device initially contains 1.2kg of saturated liquid water at 220oC. Now, heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. Determine (a) the final volume of the tank, (b) the final temperature (c) the final pressure, and (d) the change in internal energy of the tank. To check your work, enter the final pressure in kPa in the box below. Also, sketch this process on a T-v diagram.

2.Water, initially saturated vapor at 14.6 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored. 3.A piston-cylinder assembly contains 4 kg of water at 211.4oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.8 bar. During compression, there is a heat transfer of energy from the water to its...

Arigid tank of volume 0.5 m3 is connected to a piston-cylinder assembly by a valve as shown in the diagram below. Both vessels contain pure water. They are immersed in a constant- temperature bath at 200°C and 600 kPa. Consider the tank and the piston-cylinder as- sembly 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...
