X* (80/100)-x * (80/100 * 20/100) = 16.
So x = 25.

20/(0.8*0.8)=25.
80% Conveyance efficiency.
80% Irrigation Efficiency.

Not getting, please anyone explain.

16/(0.8 *0.8) = 25.
80% = 0.8,
100 - 20 % = 0.8.

Thanks all of you for explaining the answer.

0.8x - (0.8x * 0.2) = 16.
Then, x = 25cm.

ir efi = 80% = 0.8.
con efi = 100 - 20 = 0.8,
Overall E = 0.8 * 0.8 = 0.64,
D at outlet = 16/0.64 = 25cm.

Not understood. Please explain me clearly.

Taking 25 as a flow, loss = 25*.20 = 5.
Remain = 20 efficiency = 80%.

So .20*.80 = 16.
Answer is 25 c.m.
