Mist irrigation system

This formula helps calculate the minimum pipe size based on water flow.

Irrigation water flow: liters/second, m3/hour

Maximum speed: 1.5m/s

Minimum pipe size: mm. Minimum pipe size is understood as the inside diameter of the pipe
(ID – inside diameter)

Pressure loss: allowable (acceptable) pressure loss level


Note: The minimum pipe diameter (inside diameter - ID) is selected as the pipe size for
guaranteed a block
A given amount of water flows through the pipe wall at a suggested speed of less than 1.5m/s

The optimal pipe diameter is a reasonable diameter and balance between technical factors and factors
Investment costs, weak
operating costs factor.

Technically, the optimal pipe size is the pipe size that allows a quantity of water to pass through with velocity and
pressure loss level
acceptable.

In addition, it is also related to pipe length. Usually a pipe is longer then
Needs large diameter
more.

Optimum Pipe Sizing Formula is somewhat different from the Sizing Formula
Minimal simple tube
above when there are additional limits on pipe length and pressure loss limits. At work
pipeline calculation
The minimum optimum is simply based on the water flow through the pipe.

Variables in the formula

• Irrigation water flow: liters/second, m3/hour


• Tube size: mm. Pipe size is understood as the inside diameter of the pipe (ID - inside
  diameter). For example, a 60mm tube, thick
  2.5mm means the remaining inner diameter is 60mm-5mm*2 = 50mm.


• Water velocity: m/sec. Shows how many meters the water is pushed in one second.
  

Hypothesis: plastic pipe.
