P1.15 Mott [50] recommends the following formula for the friction head loss hf, in ft, for flow through a pipe of length Lo and diameter D (both in ft): where

Q is the volume flow rate in ft'/s, A is the pipe cross-section area in ft“, and C, is a dimensionless coefficient whose value is approximately 100. Determine the dimensions of the constant 0.551. h_{f}=L_{0}\left(\frac{Q}{0.551 A C_{h} D^{0.63}}\right)^{1.852}
