It calculates the pressure drop (or dynamic pressure drop)
of a piece of pipe 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.
Selection of pipe kind
Absolute roughness of the inner wall
Selection of pipe dimensions
Required flow rate
Kind of fluid
Working temperature of the fluid
Viscosity of the fluid
Density of the fluid
Rectilinear pipe length
90º elbow joint
Bend with big radius
|Fluid velocity in the pipe||m/s|
|Relative roughness in the inner wall||r/d|
|Friction coefficient (Colebrook Whine)|
|Resultant dynamic pressure drop||kg/cm2|
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).
For angle joints are meant joints with not started fluid (without coving).
For 90 degrees joints are meant the elbow joints.
