A permanent matured orchard has a tree spacing of 4 m×5 m. Each tree has a shading area of 40% to be irrigated with the ‘pig tail’ pattern multi-exit drip emitters. The effective wetting geometry of each emitter is 2 m×2 m. The emitters have discharge constant and exponent of 0.3 and 0.6, respectively. The coefficient of variation of emitter discharge is 0.06. The average and minimum operating pressures are 120 kPa and 100 kPa, respectively. The emission uniformity of the emitters is
Correct : 84.5
