It's always interesting to learn about thermodynamics and this lesson about momentum is interesting. I have read a little in the past about momentum in physics so I don't know so much about it. But still thanks for the lesson and have a great day.

Thanks @aloysiusmbaba for stopping by. There are two interesting things to understand in this article.
1-The momentum equation is similar to that of forced convection, but in this case mass forces will have to be considered.
2-The expansion coefficient represents the percentage change in density for a change in temperature (it has a dimension equal to the inverse of a temperature)
Below is the mathematical expression of the expansion coefficient.
