May be p directly proportional to 1/n3d5.

Which type of flow should be given? Here it is not given.

Head loss in pipe given by= 4flv^2/2gd.
And here we can write Av=Q,
Replace v by Q/A you will get the answer.

By Huygens equation head in pipe flow is inversely proportional to the square of the diameter of the pipe, it can applicable at laminar as well as turbulent flow, so may be the answer is B.

@Majibul. You are not talking about head in pipe flow. In pipe flow. The answer given is correct. "C".

How is it 1/d^5?

H = D^2 * N^2.

D is the right answer. Am I right?
