Hydraulic CALC pro

Version Information : 3.10

* Note :

This is a PRO model of Hydraulic CALC, which is a free software.

There isn't any functional distinction with the free version except the additional service to share the calculation results.

It is beneficial to strive the free model before you purchase the PRO version.

This utility was developed mainly to offer a swift access to quite so much of formulas, theories and coefficients associated to hydraulics for civil engineers, particularly working in the subject of water supply and sewage system.

Every single formulation in this system was employed with meticulous care, however as errors may exist, subsequent examinations are beneficial.

The accuracy of this system shall be regularly updated in addition to the types of formulas provided.
