Concept explainers

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 Carnot heat pump is to be used to heat a house and maintain it at 25°C in winter. On a day when the average outdoor temperature remains at about 2°C, the house is estimated to lose heat at a rate of 55,000 kJ/h. The heat pump consumes 4.8 kW of power while operating. 55,000 kJ/h Determine the total heating costs, assuming an average price of $0.11/kWh for electricity. The total heating cost is $40.33 (You must provide an answer before moving to the next part.)

Ivone is an Electrical Engineer that is working at the IceCube Neutrino Observatory, which detects subatomic particles emitted by the Sun's core so that we can precisely learn its age. As the name implies, the observatory is located in Antarctica. And solar power just isn't enough to run all of Ivone's cool equipment. So Ivone convinces the scientists there to let her build a 400 MW Rankine power plant. She feels that the pressure of saturated vapor entering the turbine should be 9 MPa and the saturated liquid exiting the condenser should be 0.007 MPa. The ocean water around the plant contains glaciers year round, and is a constant 0 °C. Also, Ivone hates penguins. (They use the bathroom everywhere!) Since there is no local government to stop her, Ivone makes the cooling water exiting her power plant 100 °C in order to suffocate all fish in the area and force the penguins to move to another location. For Ivon'e power plant, calculate the following: a. Heat input from the boiler b.…
3.5 A novel heat engine is being considered for producing work from the thermal energy contained in the wastewater discharge from a large food-processing plant. On an average day, 35 ° C wastewater leaves the plant and is discharged into the ocean at 1,000 gallons per minute. If the average annual ocean temperature is 10 ° C at that location, what is the maximum power that could be produced by this heat engine? What would be the thermal cycle efficiency of your maximum power engine? You can assume that the heat capacity of water at constant pressure is constant at 4,200 J/kg K.
