Question

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 211.4^oC 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 surroundings having a magnitude of 279 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water.

4.Water, initially saturated vapor at 10.2 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the pressure at the final state, in bar.

5.Water contained in a closed, rigid tank, initially saturated vapor at 200°C, is cooled to 104.4°C. Determine the final pressure, in bar.
