I have questions about a well pump application I am working on. It consists of a well that with a submersible pump that fills a reservoir tank. As far as I know, the tank is not pressurized. Here are some values associated with the system.
- Static well level = 39 ft
- Tank Discharge level = 28 ft
- Well drawdown = 67 ft
A couple of questions I have are listed below.
Am I correct in assuming that the static head requirement for the system curve is 67 ft?
Drawdown is a function of flow, so it's considered dynamic head. I keep on getting tripped up on the difference in suction vessel and discharge vessel pressure, though. The well is open to the atmosphere so there is no suction "vessel" pressure, but the tank is closed and so I keep on thinking there might be discharge vessel pressure, but if the water is releasing into open space and then dropping to fill the tank, wouldn't this also be atmospheric pressure, unless the tank is pressurized? Appreciate the assistance.
