Determine capacity of sprinkler irrigation system to apply water at a rate of
1.25 cm/hr. Two 186 meters long sprinkler lines are required. Sixteen sprinklers are placed at 12 m intervals on each line. The spacing of line is 18 m. Also determine diameter of sprinkler nozzle, if pressure head at nozzle is 30 m and dose of fertilizer required if recommended fertilizer dose is 75kg/ha.

A canal diverted 80 liters/sec of water to the field. An area of 1.6 ha was
irrigated in 8 hrs. Depth of root zones was 1.4 m. The loss due to surface
runoff was 375 m3 . The depth of water varied linearly from 1.5 m at head to 1.0 m at tail end. Available moisture holding capacity of soil is 18 cm per meter depth of soil. Find water application efficiency, water storage efficiency and water distribution efficiency.
