Thank you. I understand your logic now. I was thinking of the process of filling the pipe. Assume the tank has 10 feet of head and a horizontal run before it drops vertically. You open the valve and there would be 10 feet of differential head (3.6 psid) accelerating the fuel through the...
Thanks for the reference to the other thread. If I fill the tank at the top, then open the valve, I think that the maximum pressure differential we can possibly see in the piping from the tank to the beginning of the vertical drop will be atmospheric (12 psia at our elevation) minus the vapor...
We didn't think about cavitation as a problem, we just were more concerned with excessive pressures and hammer. We would fill as fast as we could with the valve full open if that would work.
We want to fill an underground fuel tank with an existing 1-inch pipe which drops 1400 feet vertical before running 800 feet horizontal to the tank. We are considering using a same size batch tank on the surface with a valve there and no where else. How can we determine if we need to throttle...
