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)

Why are drip irrigation systems more efficient than sprinkler systems?
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.

How is irrigation used to bring water to dry areas?
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.
What is the purpose of a sprinkler anti-siphon valve and how does it prevent backflow in irrigation 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.
What is the most common extinguishing material used in fire sprinkler systems?
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.
What is use of sprinkler?
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.
How does sprinkler systems work?
