Motor size depends upon number of factore.
1- flow of pupm
2- required head
3- efficiency of pupm used
4- efficiency of electric motor used
The formula is
H.P required= Q.H\ 3960. Pump efficiency. Motor efficiency
where Q= GPM
H= Ft
Efficiency= In fraction( 70 % = 0.7)

Frequency drives are an adjustable-speed drive used for electro-mechanical drive systems. They control the motor speed and torque by varying motor input frequency and voltage.

The motor used in the eram is a massed produced called the Johnson Motor. You can order them by the hundreds. Because of the motor that is used with the eram you will most likely only get 3 to 5 horsepower.
A device with an overload protection used to control a motor is an Overload Relay.
Sprinkler systems are often used to water areas that have plants evenly distributed (such as a grass lawn). In this scenario a sprinkler is effective because the entire area needs water. Drip irrigation systems are more efficient when the main root areas are spread out (such as a fruit orchard) because they apply the water directly to the roots of the desired plants. This reduces the amount of evaporation loss and the loss from weed growth.
Types of Micro-Irrigation: Drip Irrigation (Both on-line and in-line systems) Sprinkler Irrigation System Micro sprinklers Micro jets Rain Guns Gravity fed Drip System Semi permanent sprinkler system.
A drip or a sprinkler or overhead irrigator is used
Irrigation systems transport water from a water source, such as rivers or wells, to dry areas using canals, pipes, or ditches. This delivers water to crops for agriculture, helping to sustain plant growth in regions with limited rainfall. Different irrigation methods include surface irrigation, drip irrigation, and sprinkler systems.
The purpose of a sprinkler anti-siphon valve is to prevent contaminated water from flowing back into the main water supply. It does this by creating a barrier that stops water from flowing in the wrong direction, ensuring that only clean water is used for irrigation.
Ordinary water is used in most fire sprinkler systems. Most fire sprinkler systems are connected directly to the same water you get from the fire hydrant, which is also often the source for drinking water as well.
Functions:To prevent soil erosion it is usedWhen soil is excessively permeableIt is used when slopes are excessiveTopography is irregular.Sprinkles the water evenly.Gives aesthetic appearance.
A sprinkler system works by pushing water through a hose or underground water pipes and releasing the water through a sprinkler nozzle. These can be used manually or automatically through electronic systems.

The process of supplying water to land by artificial means is called irrigation. Irrigation is commonly used in agriculture to provide water to crops in areas where rainfall is insufficient. Various methods of irrigation include surface irrigation, sprinkler irrigation, and drip irrigation.
