I am trying to do a fluids type equation problem in Mathcad 15 and I want units in inches per water, however it does not have those units therefore I have no clue what to do? Please help

Thank you

Your equation needs density units (dynamic pressure) to get the units correct. I've shown you a fix, but you need to understand your equation better.

Where did the "4030" come from? This is an empirical formula?

I think it is an empirical formula.

(Or a pseudoempirical one)

Kevin!

Show please the origin of this formula!

Kevin:

See the attached Mathcad file.

Should answer your question about units for the 4006 number (or 4030 depending on constants used).
