In response to Re: drop dressure
The static pressure just depends on how high the water level in the tank is above the site where the pressure is being measured. The dynamic pressure, (when water is being used), depends on the pipe diameter and the smoothness of the pipe interior. There are charts to determine water flow under various pressures and friction coefficients. For the static pressure, the pressure is about one pound per 2 1/4 feet of elevation.
: Terry,
: Is there a formula to figure out the end pressure of a water line coming from holding tank at a higher elevation.
: Does tank capacity, pipe diameter matter?
: or is it just slope and distance.
