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.

by liquid water. Find (a) the amount of steam that has entered the tank, and (b) the amount of heat transfer.

3) In a fixed volume container with a volume of 0.1 m^3, initially there is saturated water vapor at 130°C. The vessel is connected to a pipe through which steam flows through a valve at 2 MPa pressure and 350°C temperature. Then the valve opens and steam enters the container. Meanwhile, the temperature of the steam in the container remains constant at 130°C due to the heat transfer to the environment. When it is observed that 3/4 of the water in the container covers the liquid phase by mass, the valve is closed. Calculate a) the final pressure in the container, b) the mass of steam entering the container, c) the heat transfer to the environment.
A rigid vessel contains 5kg of wet steam (water) at 0.4 MPa. After the addition of 9585 kJ of heat, the steam has a pressure of 2.0 MPa and a temperature of 7000C Determine (a) the initial quality, (b) internal energy, and (c) specific volume of the steam.
A cylinder-piston device provided with stops, so that the water supports the weight of the piston, and the force of the atmosphere,It contains water, initially at 300 kPa and 0.5 m3 / kg. The water is heated to a saturated steam condition and the plunger rests on the stops. With the plunger on the stops, the water is heated up to the pressure of 600 kPa. In the P-V and T-V diagrams, with respect to the saturation lines, the process curves go through the initial and final states of the water. On both T-V and P-V diagrams draw the isotherms that pass through both states, and show their values in ° C, in the isotherms. (see img 1)
(1) Water that has an initial volume of 140 L at 70°C with a quality of 28 percent is contained in a spring-loaded piston-cylinder device. This water is then heated until the pressure rises to 400 kPa and the temperature reaches 1100°C. The total amount of heat transfer during this process is:
A rigid tank of volume 0.018 m is connected through a closed valve to a vertical cylinder fitted with a freely moveable frictionless heavy piston of area 0.02 m?. Initially, the rigid tank is filled with air at 500 kPa and 25 °C while the cylinder has air of volume 0.015 m³ at 25 °C. In the vicinity, the ambient air pressure is 100 kPa and the gravitational acceleration is 9.81 m/s. It is given that the 2 air can be assumed to behave as an ideal gas with the gas constant R = 0.287 kJ/kg.K. (a) At this initial state, determine the air pressure in the cylinder. The valve is then slowly opened and left opened, allowing the pressurised air from the rigid tank to flow gently into the cylinder, thus lifting the piston. This process continues until the piston comes to rest with the whole connected system reaching its final state of equilibrium. During this entire process, the air temperature in the rigid tank and the cylinder remains constant at 25 °C. (b) Find the mass of the air transferred…
An insulated piston-cylinder device contains 4.5 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 20 A flows for 42 min through a resistor placed in the water.
