It calculates the pressure drop (or dynamic pressure drop)
of a piece of oleodynamic system with constant section.
For circuits composed of multiple traits in series with different sections is necessary calculate them separately and sum the results related to each section.
Kind of pipe
Absolute roughness of the inner wall
Required flow rate
Kind of fluid
Working temperature of fluid
Linear pipe length
Curves derived from a bent pipe
|Fluid velocity in the pipe||m/s|
|Relative roughness of the inner wall||r/d|
|Friction coefficient (Colebrook Whine)|
|Resultant dynamic pressure drop||kg/cm2|
Selection of the kind of circuit is useful to indicate the useful field for each application avoiding undesiderable effects such as back pressure at drain pipe, cavitation at suction pipe or accentuated noise on the sending pipe.
Joint with an R/D ratio higher than the maximum avaiable can be neglected (add the development of the joint on the length of the pipe).
The apps about pressure drop.
