Reduce Water Pressure to Save Water and Energy Without

High water pressure due to low system demand especially at night is a significant cause of non revenue water loss and associated expenses. Aging pipelines, joints, flanges and shifting ground all contribute to unseen and unmeasured water loss.

Flow and pressure drop in valves and fittings. Valve

Pressure drop or head loss is proportional to the velocity in valves or fittings. For the most engineering practices it can be assumed that pressure drop or head loss due to flow of fluids in turbulent range through valves and fittings is proportional to square of velocity.

What You Can Do About Low Water Pressure

Water pressure refers to the amount of force that is put on the water to make it move from one place to another, or to the amount of force the water exertsg out of the pipe. Water flow is the result of pressure on volume. Volume is the amount of water available for delivery, and pressure is the force exerted on it.

Relationship Between Pressure Drop and Flow Rate in a

Head loss does not reduce the fluid velocity consider a constant diameter pipe with a constant mass flow rate, and it will not be effect the elevation head of the fluid consider a horizontal pipe with no elevation change from inlet to outlet. Therefore, head loss will always act to reduce the pressure head, or static pressure, of the fluid.
