WebNo, Carnot engine only exists in ideal situation. That is we are assuming that there are no external interaction (e.g. heat transfer). This is impossible in real life ( 2 votes) Flag … WebA heat reservoir (Figure 5.3) is a constant temperature heat source or sink. Because the temperature is uniform, there is no heat transfer across a finite temperature difference and the heat exchange is reversible. From the definition of entropy ( ), where is the heat into the reservoir (defined here as positive if heat flows into the reservoir.)

The amount of heat taken in it in one second to produce useful mechanical work at the rate of 750 J is … WebProblem 5.2 - A heat pump is used to meet the heating requirements of a house and maintain it at 20°C. On a day when the outdoor air temperature drops to -10°C it is estimated that the house looses heat at the rate of 10 kW. Under these conditions the actual Coefficient of Performance (COP HP ) of the heat pump is 2.5.

Web23 Feb 2024 · Steps Involved in Carnot Cycle. For an ideal gas operating inside a Carnot cycle, the following are the steps involved: Step 1: Isothermal expansion: The ideal gas is taken from P 1, V 1, T 1 to P 2, V 2, T 2.Q 1 amount of heat is absorbed from the reservoir at temperature T 1.The gas then expands and isothermal. WebA Carnot engine is an idealization of real engines, in actual practice it does not exist. As any heat engine, a Carnot engine receives an amount of heat Qh from a high-temperature heat reservoir, performs an amount of work W on its surroundings, and delivers remaining heat to a low-temperature heat reservoir.
