Eight (8) kilogram of saturated vapor of refrigerant R-134a is contained in a closed frictionless piston-cylinder device at a pressure of 200 kPa. Heat is then transferred to the refrigerant. At the end of the process, the refrigerant has a temperature of 70 °C. Determine the amount of heat that is transferred during the process. Also, show the process on a T-v diagram with respect to the saturated liquid and vapor lines. (35 points).

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...

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 125 kPa. Initially. 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 10%. We denote the...

An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
