When the friction head loss of water flowing through a circular pipe with diameter D (m) and length L (m) is hf (m) and friction factor is f, the average velocity V (m/s) of water flowing through the pipe can be calculated as follow.

hf = f*(L/D)*(V^2/(2g))

V^2/(2g) = (hf/f)*(D/L)

V = sqr(2*g*hf*D/(f*L))

*** Âü°í¹®Çå[References] ***

V = sqr(2*g*hf*D/(f*L))
