FIGURE 5. Resistance coefficients of pipe fittings. To convert to SI in the equation for h, v^2
would be measured in m/s and feet would be changed to meters. The following values would
also be changed from inches to millimeters: 0.3 to 7.6, 0.5 to 12.7, 1 to 25.4, 2 to 50.8, 4 to
101.6, 6 to 152.4, 10 to 254, and 20 to 508. (Hydraulic Institute.)
