Head psa(suction surface pressure) = 2.31xP/specific gravity
This is one of the factors to calc NPSH. Shows how much head is pushing liquid through the pump.
What does the specific gravity have to do with surface pressure of a liquid before it goes into the pump? Isn't it just involving the...
1. Homework Statement
This isn't really a problem but an example in an online lecture. I'm trying to understand everything for when I get to harder questions but am having trouble understanding the "d/b" part of the equation.
How does dividing d by b help solve for the...
I think haruspex may be correct. They are two separate FBD and the answer to the question is that neither their net force or moment are the same. I may need to over this again.
If no new comments are posted, thanks for your time!
I can see how the net force is not the same but I'm not getting the net moment.
The Attempt at a Solution
12mm x 10N = 120N-mm. How do these two FBDs not have the same net moments.
Thanks for any help!
