INDIAN GEOGRAPHY

Detailed explanation-1: -In the sprinkler method of irrigation, water is sprayed into the air and allowed to fall on the ground surface somewhat resembling rainfall. The spray is developed by the flow of water under pressure through small orifices or nozzles. The pressure is usually obtained by pumping.

Detailed explanation-2: -Most spray and rotator heads are designed to work their best at about 30 psi. When pressure is lower, the watering radius will be reduced, so you may need to place your heads closer together to get the coverage you need. Higher pressures – those above about 40 psi – will cause the head to mist or fog.

Detailed explanation-3: -The optimum operating pressure for most residential sprinkler heads is between 30 and 50 pounds per square inch (PSI). With correct water pressure, each head will perform the way they were designed, and the result will be even spray-patterns and efficient use of water.

Detailed explanation-4: -Fluctuating water pressure can damage the irrigation system when pressure gets too high. High water pressure also causes loss of irrigation efficiency since water will leave the nozzle in a fine mist and blow away without irrigating the landscape.

Detailed explanation-5: -Adjust the pressure regulating dial on your control module. If the pressure is a little low, try turning this dial to increase the pressure manually. For a fixed spray system, aim for 20-30 psi per sprinkler. On a rotor/pop-up system, shoot for 30-60 psi. Irrigation and drip systems require 20-40 psi.
