DZETACAD: pressure drops calculation using the networks designed with AUTOGAINE and AUTOTUBE Example of a presentation and of an Excel pressure drop table made with DZETACAD

Compute pressure drops in a network

Objects drafted with AUTOGAINE and/or AUTOTUBE already contain ample information embedded at the time of their creation.
A specific tool lets you add missing information that might be needed for computations (length of vertical ducts, flow, direction of flow).
Select specific segments of the route for pressure drops computation.
Automatically locate each part and create a ready to print layout of a chosen network route.
Excel spreadsheet listing singular and linear pressure drops.
Tables and computation procedures taken from reference studies in the trade. (Ref.: MEMENTO of pressure drops by I.E IDEL’CIK, PORCHER air conditionning courses).

 

Compute friction factors using the COLEBROOK formula, taking into account the following factors:

Roughness coefficients of materials.
Duct shapes.
Altimetry and humidity for air computation.
Fluids temperature.


Computation of DZETA coefficient

Tables and computation procedures taken from reference studies in the trade. (Ref.: MEMENTO of pressure drops by I.E IDEL’CIK, PORCHER air conditioning courses).
Informs the user on the chosen computation method.
Takes into account the direction of flow in each part.
Instant reading on the DZETA coefficient and pressure drop of fittings, directly into the drawing.
Allows to force the DZETA coefficient for special parts.
