Hey #engineering folks... I need to know the water pressure on point B... what eq. or method I can use to get it? Point I is the exit point of a 750L water reservoir tank I-A: dH = -4m, pipe length = 20m, pipe diam. 1'' A-B: dH = 2m, pipe length = 7m, pipe diam. 1/2'' Point B is a water shower where I need enough water pressure :)
I think you are missing the height of the water tank (or the water depth) which defines the maximum water pressure at point I. Add the Atmospheric pressure at your altitude. Then you need the pressure drop/head loss caused by the length of pipe, then add it all together. Sorry I don't remember exactly how this is calculated, but it's a very frequent case in hydraulics.
So it would be something like atmospheric pressure + (water height in the tank + 2 (4-2) (in pressure units or height), then subtract pressure drop/head loss from the pipe length. I recall some tables used to obtain pressure drop from pipes.
