- Q2/ In a design of a portable sprinkler system, the following information is given: • • The sprinklers are distributed in a square pattern with radius of the wetted circle of the sprinkler=15 m Consumption rate = 10 mm/day Efficiency of irrigation = 60% Net depth of irrigation (NDI)= 80 mm. Find the following: 1-Sprinkler application rate if HRS = 11. 2-Number of pipes required for irrigation. (50 Marks) 3-Discharge of sprinkler, diameter of nozzle, and the working head pressure if C=0.90. 4-Diameter of the sprinkler pipe for Slope=0. 5-Pressure head at the inlet and at the dead end of the sprinkler pipe for Slope=0.

Not all figures are to scale. Assume any values if you need them. Q1/ A farm with dimensions and slopes (50 Marks) = shown in the figure below. If you asked to design a border irrigation system and if you know that Net depth of irrigation - 96mm .Manning coefficient = 0.15, Time of work in the farm is 6 hours/day. Design consumption use of water from the crop (ET) 16 mm/day, Width of the agricultural machine equal to 2.5m, Equation of infiltration - D= 12-05 and Efficiency of irrigation= 60%. You can neglect the recession lag time.
