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.

3- A piston cylinder device is equipped with a paddle-wheel driven by an external motor and is filled with gas. The walls of the cylinder, the piston, and the paddle-wheel and its shaft are all made of a material which is very good insulator. The system contains 50 g of gas.Initially the gas is in state A. The paddle-wheel is then operated, but the piston is allowed to move to keep the pressure constant. Then the paddle-wheel is stopped, and the system is found to be state B. There is very little friction between the piston and cylinder walls. Determine the energy transfer in joules along the paddle-wheel shaft.

A cylinder-piston assembly contains 1 kg of a substance at 100 kPa. The initial volume is 0.5 m3. Heat is transferred to the substance in an amount necessary to cause slow expansion at constant temperature. This process ends when the final volume is twice the initial volume. Determine the magnitude of the heat transferred if the substance is: a) Nitrogen (ideal gas. Assume constant specific heat) b) Water

1 - Consider 2 kg of water in a cylinder blocked by a piston at 20 C, 200 kPa. Water is heated and piston starts to rise. When the piston reaches the blocks, the volume of water has doubled. Heating continues until the pressure also doubles. Calculate the work done by water and the amount of heattransfer. Consider the case that the piston is restricted by the linear spring. Initially the spring is at rest. Water is heated until the piston reaches the blocks. Just before it hits the blocks the pressure is twice the initial pressure. Calculate the work done by water and the amount of heat transfer by the time the piston reaches the blocks. 7 D H₂0
