1. A piston with stops containing water goes through an expansion process through the addition of heat. State 1 the pressure is 200 kPa and the volume is 6 m3. After half of the heat has been delivered the piston hits the stops corresponding to a volume of 8 m3. After all the heat has been delivered, state 2, the pressure is 500 kPa with the piston resting on the stops. What is the work? Draw the PV diagram to help determine it.

A piston–cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. a) Determine the final temperature. b) Determine the work done during this process. c)...

Consider a piston cylinder with a set of stops as illustrated in Figure Question 4 filled with CO2. Initially, the pressure, temperature and volume of the CO2 is 128 kPa, 135°C and 0.038 m', respectively. The piston cylinder then undergoes the polytropic expansion until the piston head reaches the set of stops. At this position, the pressure and temperature of the CO2 is 87 kPa and 68°C, respectively. The heat is then added to the CO2 until the temperature reaches...

A piston–cylinder device initially contains air at 150 kPa and 27 °C. In this state, the piston is resting on a pair of stops, and the enclosed volume is 400 litres. The mass of the piston is such that a 200 kPa pressure is required to move it. The air is now heated until its volume has doubled. Sketch the process on a P-V diagram and determine (a) the mass of air and the final temperature, (b) the work done...

Problem 1 A piston-cylinder system contains a paddle stirrer (a paddle with blades that can stir the contents of the cylinder). The cylinder contains a gas that is initially at 150 kPa and occupies a volume of 0.196 m3 . The piston is unrestrained and has a cross-sectional area of 0.196 m2 . 20 kJ of electrical energy is supplied to the paddle stirrer, resulting in the piston moving up by 0.2 m. During this process, 5.27 kJ of heat...
