find the formula for the head lost of a water supply network?

Question

we have general height of fall (H=6m) and have 4 bands of water supply network with 1200m long pipe scheam.So find the (hi) height of current point at free fall?Find the total head loss of the network?

Answer 1

Your head loss is going to be the the total weight of the water columns (height X area X density) between the inlet and the outlet.

The height of the current point at freefall is the head required by the pump beyond the inlet pressure supply to provide the required pressure at the outlet. It is the pressure expressed as weight of the water column divided by the outlet area.
