Duly noted. Thanks again, good sir.

Thanks for your kind reply, Jambaugh. Interesting your use of an electrical circuit analogy, and I think it's apropos. BTW, it strikes me that, to the extent that all pumps - in moving fluid - create both suction (upstream) & pressure (downstream), this is related to Newton's 3rd Law of...

This conundrum will sound hypothetical, but it represents a real-world problem: You have a pump sucking water through the same diameter line from the same level in 2 different places in a pool. FWIW, the pump is a Hayward Super Pump Series Model SP2607X102S...

My earlier curiosity notwithstanding ('b' in Eqn. 1), if any of you are feeling really lazy, here's a super simple way to compute the volume of the spherical cap: http://www.1728.com/sphere.htm :wink:

Perfect, Ben. The link you provided refers to the shape as a spherical cap (unsophisticated, I was thinking of a soup bowl). Not sure how it's derived from integration (academic to my main interest) but Eqn. 2 is exactly what I'm looking for. As a curiosity, it note in Eqn. 1 that 'b'...

Firstly, I'm a newby to PF. Secondly, I've studied calculus (2 semesters) but it's been >35 years. I'm interested in deriving a simple formula for computing the partial volume of a sphere. Such a volume would be from the surface to some point along its radius toward the center. Crudely...
