Nozzle head = total head- loss of friction head.
For maximum efficiency, Total head H = 3 hf,
V2/2g = 2(4flv2/2gd),
V = Q/area and solving we get answer.

First you need to know what is the maximum power transmitted through pipe and then equate it to the Bernoulli equation.

There's another formula for head loss by Darcy h = 8fLQ^2/^2D^5.
But I don't understand how they have used it to get the answer. Please anyone explain.

When delta p = f l/d v2/2g. So how can we applied Bernoulli equation?
