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 water cooler for drinking water should cool 25 L/h water from 18 C to 10 C while the water reservoirs also gains 60 W from heat transfer. Assume that a small refrigeration unit with a COP of 2.5 does the cooling. Find the power input to the unit.
Through a combustion of a fossil fuel at 35000C, an engine receives energy at a rate of 3000Btu/s to heat a steam to 15000C. There is no energy loss during the combustion process, the steam in turn produces 1000Btu/s of work and rejects the remaining energy to the surrounding at 3000C, What is the thermal efficiency of the plant? What is the reversible work and Carnot efficiency? What is irreversibility?
Two reversible cycles are in series, each process doing the same net work, Wcycle. The first cycle receives energy QH by heat transfer from a hot reservoir at 1000°R and energy Q is reinjected by heat transfer to a reservoir at an intermediate temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and reinjects the QC energy by heat transfer to the reservoir at a temperature of 400°R. All energy transferred is positive in the direction of the arrow. Determine: a) the intermediate temperature T, in °R, and the thermal efficiency for each of the two cycles; b) the thermal efficiency of a simple reversible cycle operating between the hot and cold reservoirs at 1000°R and 400°C, respectively. Then determine the net work done by the simple cycle, expressed in terms of the net work done by each of the two cycles, Wcycle.

In the following problem, consider the human body as a heat engine with efficiency e = 0.2 that can take in energy as food Qh, perform work W, and generate heat Qc. This heat expelled from our muscles (Qc) is an important component of maintaining a constant body temperature, which necessitates a balance of energy intake and output. In order to calculate the energy intake Qh, you will use the table above listing activity factors for selected activities, for a person with a BMR of 1440 kcal/day. For example, the energy required to stand per hour would be (fstand)(BMR) = (1.7)(1440 kcal/day) (1day/24 hours) = 102 kcal/h. For each scenario, calculate the 24 h number of bowls of cereal that must be consumed per hour (1 bowl = 100 kcal) to perform the required activity (Qh) Determine whether you have an energy deficit or surplus by considering the heat generated by your muscles (Qc), the heat loss from conduction, and the heat loss/gain from radiation We will consider heat loss from…
