I think D^5 is right answer.
Because from similarity law come the equation of power coefficient P/(N^3 D^5) that's it.

Ans: C is correct.
i.e d^3--p=TW=(Tou*pi*d^3/16*T)*(v/r).
i.e d^3--p=TW=(Tou*pi*d^3/16*T)*(v/r).

@Safy.
I think its d^5.
Because p/(N^3*D^5) = Constant.
I think its d^5.
Because p/(N^3*D^5) = Constant.
