In a relational diagram, a constant is a fixed value that does not change regardless of the variations in other variables or parameters within the system. It is often represented as a specific data point or a parameter that remains the same across different instances of the relationship being modeled. Constants help define the relationships and constraints within the diagram, ensuring consistency and clarity in the representation of the data structure.

T-S diagram of in compressible fluid flow?
In the T-S diagram for incompressible fluid flow, the specific volume remains constant, resulting in vertical lines on the diagram. The process line in the T-S diagram would be a vertical line, parallel to the entropy axis. This is because the entropy remains constant for incompressible flow.

Line of constant pressure shown on the surface pressure diagram are called isobars. Isobars show areas of high pressure and areas of low pressure. The surface pressure diagram can be used to predict weather patterns.
How do you document a database?
Two standard ways to document a database are to create a relational diagram and a data dictionary.A relational diagram will display all the tables in a database with links to joining tables utilizing the primary and foreign keys.
