But @Rosh.
Here the water depth is asked for 80% efficiency so 20cm is enough. Don't it is?

@Anil.
What if efficiency is 80% and conveyance losses is 12%?

Depth of water required considering conveyance losses = 16/0.8 = 20 cm (20% is lost in conveyance means only 80% in reached. So we have to provide more depth of water).
Irrigation efficiency is 80% (means if I provide 20 cm depth of water then only 80% land will get irrigated).
To make 100 % irrigation, Depth of water from canal outlet = 20/0.8 = 25 cm.
I hope its clear.

Crop water requirement ETo = Gross irrigation requirement*Irrigation efficiency.
So 16*80% = 10.4.
So 16*80% = 10.4.

Hence, after losses = X-X/5 = 4X/5.
= 4X/5*80/100 = 16.
X = 25.
= 4X/5*80/100 = 16.
X = 25.
