69. Evaporation in a 19.77 acre farm is 7mm/day and percolation losses is 2 mm/day. What is
the design discharge of a canal to be able to deliver a 5-day requirement of the farm in 24
hours. If irrigation efficiency is 75%.
a) 150m3/hr
c) 140 m3/hr
b) 175 m3/hr
d) 200m3/hr
70. A 50 ha plantation is to be irrigated by furrows. The depth of root zone is 1m. the
consumptive use is 8mm/day, the readily available moisture is 15cm/m, the losses due to deep
percolation and conveyance are 15% and 10%, respectively. Estimate the required irrigation
capacity in m3/s:
