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.

A piston-cylinder device as shown in Figure 1-7, initially contains 0.75 kg of refrigerant- 134a at 120 kPa and 20°C. Heat is now transferred to the refrigerant from a source at 150°C, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 140 kPa. Heat transfer continues until the temperature reaches 90°C. Assuming the surroundings to be at 25°C and 100 kPa, determine: (a) the work done, (b) the heat transfer, (c) the exergy destroyed, (d) the second law efficiency of this process.

a) A gas is trapped in a piston-cylinder device. The initial pressure and temperature of the gas are 500 kPa and 300 K, respectively. The system undergoes an isothermal expansion process, in which 15KJ of boundary work is done by the gas and 3KJ of paddle-wheel work is done on the gas. Determine the amount heat transfer during this process. Explain the direction of the heat transfer.
Please AnswerSteam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s and leaves at 375°C and 400 kPa while losing heat at a rate of 26.5 kW. For an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit. Use steam tables. The velocity of the steam at the nozzle exit is m/s. The volume flow rate of the steam at the nozzle exit is m3/s.
An inventor claims to have devised a process using only saturated steam at 100C which by a complicated series of steps, make heat continuously available at T of 177C. He claims further that, for every kilogram of steam taken into the process, 1800 kJ of energy as heat is liberated at this higher T of 177C. Show whether or not such a process is possible. In order to give the inventor the benefit of any doubt, assume cooling water to be available in unlimited quantity at 0C. topic: introduction to chemical engineerint thermodynamics

A 50-L electrical radiator containing heating oil is placed in a well-sealed 75-m3 room. Both the air in the room and the oil in the radiator are initially at the environment temperature of 6°C. Electricity with a rating of 2.4 kW is now turned on. Heat is also lost from the room at an average rate of 0.75 kW. The heater is turned off after some time when the temperatures of the room air and oil are measured to be 20°C and 60°C, respectively.
