SPECIFICATION SHEET

Compute pressure drops
in a network
•tObjects drafted with AUTOGAINE and/or AUTOTUBE already t
t contain ample information embedded at the time of their t
t creation.
•tA specific tool lets you add missing information that might t
t be needed for computations (length of vertical ducts, flow, t
t direction of flow).
•tSelect specific segments of the route for pressure drops t
t computation.
•tAutomatically locate each part and create a ready to print t
t layout of a chosen network route.

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

Computation of DZETA
coefficient

•tRoughness coefficients of materials.

•tInforms the user on the chosen computation method.

•tDuct shapes.

•tTakes into account the direction of flow in each part.

•tAltimetry and humidity for air computation.

•tInstant reading on the DZETA coefficient and pressure drop t
t of fittings, directly into the drawing.

•tFluids temperature.t

•tTables and computation procedures taken from reference t
t studies in the trade. (Ref.: MEMENTO of pressure drops by t
