Head loss , hi Head loss in a pipe fitting is proportional to the velocity head of the fluid flowing through the fitting Kyu? --(E9.2) 2g Where Ky is the fitting factor (loss coefficient) , u is the mean velocity of water through the pipe (m/s) and g is the gravitational acceleration , m/s?. where L= Length of pipe between tappings (m) = 1 m for all pipes d=internal diameter of the pipe (m) = 17.5 mm u= mean velocity of water through the pipe (m/s) g=9.81 m/s? fpipe friction coefficient 2. The mean velocity (u) is obtained from 4Q ...(Eq.4) πd2 where Q is the volumetric flow rate in mºs and d is the internal diameter of the pipe in m. 3. The Reynolds number (Re) is defined as pud Re ...(Eq.5) u= M where p is the density of water (1000 kg/mº), u is the mean velocity of water through the pipe in m/s, d is the internal diameter of the pipe in m, and u is the dynamic viscosity of water at 20°C (1.002x10 Ns/m?).
