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.

Q1. (Reading: Çengel and Boles, Thermodynamics: An Engineering Approach, 8th Ed., Pages 307-311) The amount of energy waste by a refrigerator increases by a number of malpractices. For example; opening the refrigerator door frequently will increase energy waste as the warmer air outside replaces the cool air inside. It is also not recommended to place the hot foods into the refrigerator before cooling them to the room temperature. Imagine a typical household refrigerator with an internal temperature of 4 °C. The refrigerator has a coefficient of performance of 1.4. The internal dimensions of this refrigerator are 186 cm (height) x 84 cm (width) x 75 cm (depth). The half of the refrigerator volume is used for storing food items. The air filling the other half of the refrigator volume contains 0.004 kg moisture/kg air on average. While the moisture content of the air in the kitchen is 0.01 kg/kg air, the temperature and pressure in the kitchen are 23°C and 97 kPa, respectively. Assuming…
