Carnot Cycle Pv And Ts Diagram

Q 4 1 are equal regenerative ericsson cycle will become carnot cycle because heat energy will be added from an external source at constant temperature and heat will be rejected too to an external sink at constant temperature and hence regenerative.
Carnot cycle pv and ts diagram. P v and t s diagrams are often used to visualize the processes in a thermodynamic cycle and help us better understand the thermodynamics of engines. The carnot cycle is often plotted on a pressure volume diagram pv diagram and on a temperature entropy diagram ts diagram. Now we discuss the t s diagram of a carnot cycle as shown in fig.
A carnot cycle steam as a working substance is represented on the p v and t s diagram in figure. This cycle is designed by carnot who was the first scientist to analyze the problem of the efficiency of a heat engine ignoring its mechanical details he focussed his attention to the basic features of a heat engine. The carnot cycle describes the operation of refrigerators the otto cycle describes the operation of internal combustion engines and the brayton cycle describes the operation of gas turbine engines.
If we think the concept of regeneration where area under 2 3 i e. Area 1 a b 4 1 is the heat added to the refrigerant from the cold region per. The gas becomes cold and hot after adiabatic expansion and compression respectively.
In a carnot cycle the working substance is subjected to a cyclic operation consisting of two isothermal and two adiabatic processes. Carnot cycle pv ts diagram pv diagram of otto cycle. The carnot cycle is often plotted on a pressure volume diagram pv diagram and on a temperature entropy diagram ts diagram.
Diagrams areas since the carnot vapor refrigeration cycle is made up of internally reversible processes areas on the t s diagram can be interpreted as heat transfers. Q 2 3 and area under 4 1 i e. Like the pv diagram the processes for a ts diagram of a complete carnot cycle is similar such as line ab isothermal expansion where the temperature t 1 constant.
The above diagram represents a graph between temperature t and entropy s for a reversible carnot cycle. So no contribution to q r e v comes from the adiabatic. The otto cycle is often plotted on a pressure volume diagram pv diagram and on a temperature entropy diagram ts diagram.
