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

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.

Solve using dimensional method.
=> f is unit less.
=> D^5/l has dimension L^4.
=> f is unit less.
=> D^5/l has dimension L^4.
