Flow Velocity & Head Loss Through FittingsFigures in m/sec

Fitting Type Factor To calculate head loss through fitting:

Bend - 45o 1.02 1. Knowing flow rate and pipe size, determine

Bend - 90o 2.04 2. Calculate the square of the velocity

Elbow - 45o2.04 3. Multiply this by the factor for the fitting.

Elbow - 90o5.10 4. Divide this number by 100. This is the hea
