To obtain friction factor, f, we need to know the Q, D, and ks in a given fluid flow. But if Q is unknown, select the most appropriate answer. D3/2 2ghf Still, we can get f by using k/D (on the right axis) and Ref = (on the top axis). O When Q is known, but D is unknown, we can get f from the Moody diagram. When Q is unknown, we cannot get Re, so we cannot get f from the Moody diagram. O None of the answers are correct.
