Pump and piping selection

1. Load: The head indicated on the pump nameplate is the unknown amount of frictional loss in the pipeline. When calculating the field head, measure the vertical height of the water from the water level to the highest point of the pipeline at the minimum water level in the well (when the water level in the water tower is higher than the highest point of the pipeline, calculated from the maximum water level in the water tower), plus the loss of pressure, caused by the pipeline, and then select a suitable pump.

2. inner diameter of the distribution pipe: the hydraulic loss of the pipeline is related to the inner diameter, length, roughness of the inner wall of the pipeline, the thinner the diameter of the pipeline, the longer the pipeline, the rougher the inner diameter, the greater the hydraulic loss of the pipeline. Inner diameter of the pump distribution pipe.

Pressure loss in other pipelines

It is necessary to multiply the value of the cast iron pipe by the following coefficients

PVC pipes: 0.76;

galvanized pipes: 1.17;

Easy to rust tube: 2.10;

\Heavy hose: 3.60.

Approximate method for calculating pressure loss in pipes

Bottom valve: approximately 15m - range;

check valve: approximately 10m pipe range;

Open valve: approximate 5 meter process;

Bends and bends: approaching a 5 meter pipe.
