Specific Entropy * Temperature => Specific Energy #891

Closed wiwalsh closed 3 years ago

wiwalsh commented 3 years ago

When working with fluids I represent the Enthalpy with SpecificEnergy (Energy/Mass) The Enthalpy can be calculated a number of ways, but for simplified incompressible fluids it is calculated by Enthalpy = SpecificHeat Temperature or, in UnitsNet units Specific Energy = SpecificEntropy Temperature

I can implement this if someone can point me in the right direction.

Thanks, Scott

Also: This might also be an opportunity to talk about aliases and if they have been proposed before. Specific Heat and Specific Entropy are good examples. They share all the same characteristics, but have different common names. It makes code readability less simple, and unit conversion similarly difficult. Is there a way to implement this?

Hi, sorry for late answer. I believe you can implement this by adding operator overloads to CustomCode/SpecificEntroy.cs (create the file if it does not already exist).

See https://github.com/angularsen/UnitsNet/wiki/Adding-operator-overloads

and see how it's done for other quantities.

Let me know if that helps!

As for aliases, this is a much bigger discussion worth its own issue. I believe we have discussed it loosely several times before, but not sure if we have a specific issue for that topic. Please give it a search first.
