# Hydraulic CALC

3.10 for Android

## The description of Hydraulic CALC App

Hydraulic CALC
Version Information : 3.10

This application was developed mainly to provide a swift access to a variety of formulas, theories and coefficients related to hydraulics for civil engineers, especially working in the field of water supply and sewage system.

Every single formula in the program was employed with meticulous care, but as errors might exist, subsequent examinations are recommended.

The accuracy of the program will be continually updated as well as the types of formulas provided.
