An outlet irrigates an area of 40 ha. The discharge required at this outlet to meet the evapotranspiration requirement of 40 mm occurring uniformly in 40 days neglecting other field losses is _________ Correct Answer 4.52 litres / sec

Volume of water required for evapo-transpiration = 40 x 104 x 40 x 10-3 x 103 = 16 x 106 litres Hence, the discharge required at outlet = (16 x 106) / (40 x 86400) = 4.52 litres / sec.

If total revenue from outlet X & Y in 2013 was up 1 percent from 2012, what is the ratio of revenue from outlet X in 2012 revenue from outlet Y in 2012?
A tank has an optional adjustable outlet pipe that can be attached to the tank at any height we want. This outlet pipe drains water from the tank at a constant rate, while the tank is being filled using another inlet pipe at a constant rate. If the outlet, pipe is attached at half the height of the tank, the tank, which is initially empty gets filled in 18 hours. If the outlet pipe is attached at height equal to two third height of the tank, the tank, which is initially empty, is filled in 16 hours. In how many hours will the tank, which is initially empty, be completely filled if the outlet pipe is not attached to the tank?
