Nomograph for calculating Reynolds number for flow of liquids and friction factor for clean steel and wrought iron pipe
The nomograph (Figure 1) permits calculation of the Re = 22 700 qr = 50 6 Qr = 6 31-W = dvr Reynolds number for liquids and the corresponding friction dm dm dm m a
factor for dean ^ed and wrought iron pipe. where Re = Reynolds number
The Reynolds number is defined as: d = inside pipe diameter, in.
