FK 40 - Tri-Canada

Example:
Flow rate Q = 25 m≈/h
Pipe diameter
From the diagram results:
d = 50 mm
Flow velocity v = 3.5 m/s
Loss of head H = 35 m/100 m
V
The loss of head in fittings can be determined almost exactly when using adequate pipe
lengths.
The loss of head in a fitting is considered equal to a straight pipe with corresponding
length.
This calculation is valid only for water and fluids similar to water.
With the same diameter of pipes and fittings we can simplify the calculation.
