I'm trying to design a system with an elevated water tank that feeds into an intermediate closed tank at ground level and then on to an irrigation pipe.
The reason for the elevated water tank is increased PSI. The reason for the intermediate ground level tank is increased water holding capacity without the added cost of an insanely heavy duty water tower.
My thinking is that if the intermediate tank is closed, the PSI at the end of the pipe (X), should be computed from the difference between the bottom of the tower tank and the end of the pipe.
Is that right?
