Temperature of the heater of a heat engine operating at

The heater temperature of a heat engine operating according to the Carnot cycle is Tn = 373 K, and the refrigerator temperature is Tx = 273 K. The cycle work is A = 1 kJ. It is necessary to depict this cycle in ST coordinates and determine the difference between the maximum and minimum entropy values ​​S of the working fluid. The Carnot cycle is an ideal thermodynamic cycle that consists of two isothermal and two adiabatic processes. On the ST graph, this cycle is represented by a rectangle, the upper horizontal side of which corresponds to the isotherm at temperature Tn, and the lower horizontal side to the isotherm at temperature Tx. The vertical sides of the rectangle correspond to adiabatic processes. To determine the difference between the maximum and minimum entropy values ​​S of the working fluid, it is necessary to know the entropy equation for each of the processes of the Carnot cycle and calculate its values ​​at the maximum and minimum points. Then you should calculate the difference between these values. Our digital store invites you to purchase a unique product - the course "Thermodynamics in Examples".

This product is a heat engine that operates according to the Carnot cycle. The heater temperature is 373 K and the refrigerator temperature is 273 K. The cycle work is 1 kJ.

A heat engine operates according to a cyclic process, which is a sequence of changes in the states of the working fluid that occur during one cycle. In this case, the Carnot cycle consists of two processes: isothermal expansion and isothermal compression, which occur at a constant temperature of the heater and refrigerator, respectively.

Graphically, the Carnot cycle in ST coordinates is a rectangle bounded by isotherms. The maximum value of the entropy of the working fluid is achieved on the heater isotherm, and the minimum - on the refrigerator isotherm.

S - the difference between the maximum and minimum entropy values ​​S of the working fluid is found by the formula:

S = Q / Tн,

where Q is the heat received by the working fluid from the heater, and Tn is the temperature of the heater.

When solving the problem, the laws of thermodynamics and formulas related to thermal processes are used. The calculation formula for finding S was indicated above, and the answer to the problem can be obtained by substituting known values ​​into this formula.
