Also, notice that each emitter is delivering the right amount of water to the plants and you can adjust the flow rates if necessary.
5. Structure and Working of Drip Irrigation Emitters
The basic structure of drip irrigation emitters contains some components, like: Filters, flow path, outlet. Their little description given below
A. Filters :
A small filter helps stop dirt and other particles from blocking the emitter. It also keep the water flowing smoothly without any interruptions.
B. Flow Path
Emitters have internal flow paths that control the speed and quantity of water. The way the water flows through the emitter can change, which based on if it has pressure compensation or not. Pressure-compensating emitters adjust the flow to maintain a steady amount of water. But in the case of non-pressure-compensating emitters do not adjust for pressure changes and might deliver different amounts of water depending on the pressure.
C. Outlet
The outlet is a very crucial point. where the water is released to the soil. Depending on the size and shape of the outlet determine the spread of water around the plant.
Emitters lower the water pressure from the main supply so that water flows slowly. This helps save water. So, water is soak into the soil instead of evaporating.
6. Electricity Consumption in Drip Irrigation Systems
