# What is the TS diagram of Carnot cycle?

The temperature-entropy diagram (Ts diagram) in which the thermodynamic state is specified by a point on a graph with specific entropy (s) as the horizontal axis and absolute temperature (T) as the vertical axis, is the best diagram to describe behaviour of a Carnot cycle.

## What does TS diagram represent?

A temperature–entropy diagram, or T–s diagram, is a thermodynamic diagram used in thermodynamics to visualize changes to temperature and specific entropy during a thermodynamic process or cycle as the graph of a curve.

## What are the four 4 processes in Carnot cycle describe in TS diagram?

The four stages in the Carnot cycle. (A) Stage 1: Isothermal expansion under heat input Q1, (B) Stage 2: Adiabatic expansion accompanied by a fall in temperature T1 to T2, (C) Stage 3: Isothermal compression, Q2 exhausted, (D) Stage 4: Adiabatic compression accompanied by an increase in temperature T2 to T1.

## What are the four processes that make up the Carnot cycle draw PV and TS diagram?

Name the processes involved in Carnot cycle? It involves four process: isothermal expansion, adiabatic expansion, isothermal compression and adiabatic compression.

## What is PV and TS diagram?

As described on the work slide, the area under a process curve on a p-V diagram is equal to the work performed by a gas during the process. On the right of the figure we have plotted the temperature versus the entropy of the gas. This plot is called a T-s diagram.

## What does the area enclosed by the cycle represent on a TS diagram?

The area enclosed by the cycle on the T-S diagram of reversed Carnot cycle shows the net heat input which in turn equal to net work input.

## What is entropy in TS diagram?

A T-s diagram is the type of diagram most frequently used to analyze energy transfer system cycles. … By the definition of entropy, the heat transferred to or from a system equals the area under the T-s curve of the process.

## What does the area enclosed by the cycle represent on a TS diagram of Otto cycle?

The area bounded by the complete cycle path represents the total work that can be done during one cycle. The Otto cycle is often plotted on a pressure- volume diagram (pV diagram) and on a temperature-entropy diagram (Ts diagram).

## What is a Carnot cycle What is its purpose?

Carnot cycle, in heat engines, ideal cyclical sequence of changes of pressures and temperatures of a fluid, such as a gas used in an engine, conceived early in the 19th century by the French engineer Sadi Carnot. It is used as a standard of performance of all heat engines operating between a high and a low temperature.

## What is Carnot Theorem?

Carnot’s theorem states that all heat engines between two heat reservoirs are less efficient than a Carnot heat engine operating between the same reservoirs. … is the ratio of the work done by the engine to the heat drawn out of the hot reservoir. Carnot’s theorem is a consequence of the second law of thermodynamics.

## What is a Carnot cycle explain?

: an ideal reversible closed thermodynamic cycle in which the working substance goes through the four successive operations of isothermal expansion to a desired point, adiabatic expansion to a desired point, isothermal compression, and adiabatic compression back to its initial state.

## Why is the Carnot cycle on TS plot a rectangle?

A Carnot cycle can be represented in a T-S diagram, with T along the y-axis and S (entropy) along the x-axis. … The isentropes are parallel vertical lines (by definition they are of constant entropy). Thus, a Carnot cycle is represented by a rectangle.

## What is Lord Kelvin statement?

The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.

## What is TS diagram and its importance?

A Temperature-entropy diagram (T-s diagram) is the type of diagram most frequently used to analyze energy transfer system cycles. It is used in thermodynamics to visualize changes to temperature and specific entropy during a thermodynamic process or cycle.

## What is a PV diagram used for?

A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology.

## Why Carnot cycle is a theoretical cycle?

The Carnot cycle is a theoretical cycle that is the most efficient cyclical process possible. Any engine using the Carnot cycle, which uses only reversible processes (adiabatic and isothermal), is known as a Carnot engine. Any engine that uses the Carnot cycle enjoys the maximum theoretical efficiency.

## Can you design an engine of 100 efficiency?

It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term.

## What is TC and TH in thermodynamics?

The thermodynamic temperature scale (absolute T)  Efficiency of a Carnot engine is: η = 1 – (Qc / Qh) = 1 – (Tc / Th)  The zero point of the thermodynamic scale is fixed as the T of the cold reservoir Tc at which η = 1 and hence Qc = 0 and W = Qh.

## What does the area enclosed by the sickle represent on a PV diagram?

What does the area enclosed by the sickle represent on a PV diagram? The product of pressure and volume is represented by an area on a p-V diagram. The area under the curve on a p-V diagram tells us the work done during the process.

## Which process is indicated by straight line on TS diagram?

Straight line on P – T graph for an ideal gas represents isochoric process.

## What is the significance of area under temperature entropy TS diagram?

Temperature Entropy Diagram The area under the curve 1-2 represents the energy absorbed as heat by the system during the isothermal process. The area under the curve 3-4 is the energy rejected as heat by the system. The shaded area represents the net work done by the system.

## How do you convert a PV graph to a TS graph?

Slope of constant volume line on T-s diagram = T / Cv.

1. This knowledge will be all to convert isometric process (v=constant) from P-v into T-s diagram. See Image.
2. This knowledge will be all to convert isobaric process (p=constant) from P-v into T-s. See Image.
3. • …
4. Case B: if n > ϒ, polytropic specific heat will be +ve.

## What is PV indicator diagram?

Indicator diagram (P-V diagram) A curve showing variation of volume of a substance taken along the X-axis and the variation of pressure taken along Y-axis is called an indicator diagram or P-V diagram.

## What is Otto cycle with diagram?

The idealized diagrams of a four-stroke Otto cycle Both diagrams: the intake (A) stroke is performed by an isobaric expansion, followed by an adiabatic compression (B) stroke. … The cycle is closed by the exhaust (D) stroke, characterized by isochoric cooling and isobaric compression processes.

## What does the area under PV diagram indicates in thermodynamics process?

As area under P-V diagram represent work done by gas in a thermodynamic process, area under temperature (T) entropy (S) graph represents heat supplied to the thermodynamic system.
