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