PIPELINE PRESSURE LOSS CALCULATOR IN IRRIGATION

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.
In this formula “Pipeline pressure loss calculator”, we assume the tube lies on a surface with no slope.

Variables

  • Flow rate: how many water outcome in one second, one hour (litre/second, c.m/hour)
  • Water Velocity: the speed water will run in the pipe. Normally it is not exceed 1.5m/s
  • Pipe size: ID – inside diameter (mm)
  • Pressure lost allowed: it mean that how much pressure loss through the pipe can be accepted.
  • Pipe length: The more length of the pipe lateral, the bigger pipe size required.

Pipe Water Velocity

The water velocity in a pipe can be determined using this calculation. While larger pipes tend to be costlier, it is crucial to maintain a low water velocity to minimize pressure losses caused by friction, water hammer, and changes in pipe movement resulting from water momentum alterations within the pipe.

The optimal water velocity in an irrigation system is in range 1.2 to 1.5m/sec (4 to 5.0ft/sec)

Water Velocity

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.
