What is T-s diagram in oceanography?

In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses. Temperature and salinity combine to determine the potential density of seawater; contours of constant potential density are often shown in T-S diagrams.

What is entropy in T-s 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 is PV and T-s diagram?

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.

How do Ts diagrams work?

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 is salinity give example?

Salinity is the amount of salt in something. An example of salinity is the measure of salt in a home fish tank.

What are some examples of salinity?

Salts generally found in saline soils include NaCl (table salt), CaCl2, gypsum (CaSO4), magnesium sulfate, potassium chloride and sodium sulfate. The calcium and magnesium salts are at a high enough concentration to offset the negative soil effects of the sodium salts.

What kind of diagram is a T-S diagram?

A T-s diagram is the type of diagram most frequently used to analyze energy transfer system cycles.

How does an isentropic process appear on a T-S diagram?

During an isentropic process there is no change in the entropy of the system and the process is reversible. An isentropic process appears as a vertical line on a T-s diagram. The area under a process curve on a T-s diagram is related to the amount of heat transferred to the gas.

Which is the typical shape of a TTT diagram?

The typical TTT diagram is a C shaped curve. In this case, we have used it to represent, at any given temperature, the time required for 1% transformation to complete. Step 1 (continued ….) Description of the activity Audio narration Text to be displayed Animation time : 2 seconds Points for plotting the graph.

Can a T-S diagram be constructed for any pure substance?

A T-s diagram can be constructed for any pure substance. It exhibits the same features as P-u diagrams. In the liquid-vapor region in Figure 13, water and steam exist together. For example, at point A, water with an entropy (s f) given by point B, exists together with steam with an entropy (s g) given by point C.
