## What is the meaning of isentropic process?

An isentropic process is a thermodynamic process in which the fluid or gas entropy tends to be constant. This suggests that the isentropic system is a special case of an adiabatic mechanism in which no heat or matter is transported.

**What is the area under the curve of a temperature entropy 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.

**What is T-s diagram in oceanography?**

In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.

### How do you use a temperature salinity diagram?

How to read this diagram: first, click on the image below for a full-size view. Next, choose the line corresponding to the sea surface temperature (SST). Follow this line until it intersects the density curve. At this point of intersection, draw a line vertically up or down to the salinity scale and read off the value.

**What does the area under a T-s diagram represent?**

Explanation: Heat transfer is defined as the form of energy that is transferred between two systems or a system and its surroundings by virtue of a temperature difference. this area has no meaning for irreversible processes.

**What is the other name of isentropic process?**

reversible adiabatic process

An isentropic process is also known as a reversible adiabatic process. As this is an adiabatic process so no heat enters or leaves the system. On the other hand, Isobaric is a constant pressure and Isochoric is the constant volume process and Isothermal is the constant temperature process.

## What is the equation for isentropic process?

On a p-V diagram, the process occurs along a line (called an adiabat) with the equation p = constant / Vκ. For an ideal gas and a polytropic process, the case n = κ corresponds to an isentropic process.

**Why are TS diagrams useful?**

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.

**What is the importance of TS diagram?**

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 TS diagram in oceanography?

**What is the interpretation of the area enclosed inside a cycle in a T-s diagram?**

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

**Which of the following is Isenthalpic?**

D. Isobaric. Hint: Isentropic process is a process in which the entropy remains unchanged or the change in entropy is zero. Entropy represents the disorder in a system.

## What is isenthalpic expansion?

However, the most commonly discussed isenthalpic process is the irreversible adiabatic expansion in a throttling device (e.g., flow is pushed through a small orifice or a porous plug). The process is adiabatic, since the throttle is so small that there is no time for the throughput to exchange heat.

**What is isentropic process PDF?**

During an internally. reversible, adiabatic. (isentropic) process, the entropy remains constant. A process during which the entropy remains constant is called an Isentropic process.

**What is PV and T-s diagram explain it?**

Pressure-volume (P-V) and temperature-entropy (T-S) diagrams are often used as teaching. aids to describe refrigeration processes in introductory textbooks. They trace the path of a. hypothetical element of gas as it moves through a system during a complete thermodynamic. cycle.

### What is the significance of the area of closed curve on a p-V diagram?

Solution : The area gives us the work done in the process.

**Which value S is are represented by the area enclosed by a cycle on TS and PV diagrams?**

net work

3- The area enclosed by the process curve on both T-s and P-v diagrams represent the net work of the cycle. 4- The ratio of the area enclosed by the cyclic curve to the area under the heat- addition process curve represents the thermal efficiency of the cycle.
