In a closed, pressurised system with a circulating media, the total pressure consists of two elements:
- a static pressure
- a dynamic pressure.
The dynamic pressure indicates the amount of the total pressure that results from the media’s velocity in the pipes.
The dynamic pressure is calculated using the following formula:
pd = 0,5 x ρ x v²
ρ (rho) = the density of the media
v = mean velocity in the pipe.
The dynamic pressure is used for calculating pressure loss in pipe systems.
