Hi! You are always incredible helpful. I thank you so much!
The reason of my question was to try to understand the simple sentence:
The head of the pump does not depend on the density of the fluid or generally does not depend on the fluid.
I tried to understand this from several formulas. And I was looking a formula in which the head indeed does not depend on
the density. But, I found something in my notes and in the internet please see attached.
And I was wondering if you have any extra information about the one of the two formulas (which correlated the head of the pump with the rotational velocity, etc).
Please see the attached pictures and tell me you opinion!
Thank you again for the really interesting documents.
