ok sounds good. The spreadsheet attached is my calculation for 3 iterations. I think it is correct. It would be greatly appreciated if someone could confirm the accuracy. The cells labeled "A-B in 8"' and so on use Bernoulli's equation to determine pressure rise due to the decrease in...
BigInch do you know of a method or equation to calculate this pressure drop/flow rate in each of the pipes in which I originally described? I can't find anything anywhere about this.
One thing that was really counterintuitive was when I saw a demonstration of a manifold that was not...
Wouldn't there be a pressure drop not just because of the friction of T's, but also because there is fluid lost at each penetration?
So the pressure in the header, assuming a pipe, would have a lower pressure after the first 5" penetration than before it? And so on for the other 2 penetrations?
Let's just assume the header is a large tank instead of a pipe. I'm trying to just get an idea of how the flow changes.
Also how would I account for the pressure drop across each pipe penetration if the header is in fact a 8" line fed from a pump upstream?
By the way this is schedule 40 pipe. My calculations were the following and wanted to check.
5" - 3400 GPM
3" - 920 GPM
1" - 55 GPM
This is assuming constant 70 psig pressure in the header.
I have a header of 8" line pressurized up to 70 psig with water. The end of the header is capped.
Branching off of the header are a 5" line, 3" line, and 1" line. They are all the same length of 72' and dumping to atmospheric pressure. What I am trying to determine is the flow rate in each...
