Assessment of Pressure
The pressure losses for distribution in the GF Piping Systems can be assessed by means of the
following chart or by means of the following formula:
Where:
pressure loss in a straight pipe (bar)
A pipe friction factor (in most cases 0.02 is sufficient)
length of straight pipe (m)
density of transported media (kg/m3)
flow velocity (m/s)
inside diameter of pipe (mm)
