water velocity in pipe IN AN IRRIGATION SYSTEM

The water velocity in pipes and irrigation systems is suggested by experts to reach 1.2m/sec to 1.5m/sec (4-5ft/sec). If the water velocity is lower than 1.2m/s, it means the pipe is large, whereas if it is more than 1.5m/s, it means the pipe diameter is smaller than the optimal level.
The water velocity in the pipeline is directly related to determining the size of the pipeline in the irrigation system, the pressure loss on the pipeline, which in turn directly affects the performance of the irrigation system.

Pressure loss in pipeline

Pipeline pressure loss calculator is an important formula that helps you calculate and design your irrigation system accurately.

Water pressure on a pipe is understood as a force exerted by a unit of water flowing in the pipe on the inner surface of the pipe wall.
Loss of pressure on the pipe is understood as during the process of conveying water in the pipe, part of the pressure will be lost. This pressure loss is mainly due to the friction between the water volume and the pipe wall.
This is the major factor in irrigation system to chose the pipe size and calculate the pump.

Used to calculate the velocity of water in a pipe. Bigger pipe is more expensive, but keeping the water velocity low is important to limit pressure losses due to friction, water hammer, and pipe movement due to water momentum changes inside the pipe.
