2.14 Consider the piston-cylinder arrangement shown in the figure. A frictionless piston is free to move between two sets of stops. When the piston rests on the lower stops, the enclosed volume is 400 L. When the piston reaches the upper stops, the volume is 600 L. The cylinder initially contains water at 100 kPa, 20% quality. It is heated until the water eventually exists as saturated vapor. The mass of the piston requires 300 kPa pressure to move it against the outside ambient pressure. Determine the final pressure in the cylinder, the heat transfer (in kJ), and the work (in kJ) for the overall process.

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

2.14 Consider the piston-cylinder arrangement shown in the figure. A frictionless piston is free to
move between two sets of stops. When the piston rests on the lower stops, the enclosed volume is
400 L. When the piston reaches the upper stops, the volume is 600 L. The cylinder initially contains
water at 100 kPa, 20% quality. It is heated until the water eventually exists as saturated vapor. The
mass of the piston requires 300 kPa pressure to move it against the outside ambient pressure.
Determine the final pressure in the cylinder, the heat transfer (in kJ), and the work (in kJ) for the
overall process.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.

Q/ A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar, Since all valves are closed the specific volume of steam remains constant as heat is lost. At 1.4 bar, Since v2 < v g at 1.4 bar the steam becomes wet.
