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.
