HydroCalc is a simple programme to calculate drains in full-filling and partial-filling, circular pipes. For partial-filling discharge it calculates even the associated filling level. You no longer have to pic out the values of complicated diagrams and graphs.
Optionally you can calculate with the formula of Prandtl-Colebrook (PC) or Manning-Strickler (MS). You can choose out of a list the rougness-factors graduated by the material and lifetime of the pipe. "The roughness coefficient kb by Prandtl-Colebrook or kS by Manning-Strikcler considers the wall roughness of the sewer pipe. "

The calculation is valid for steady an uniform discharge, with turbulent flow and technical rough resistance behaviour.
The full-filling discharge works without overpressure. The maximum of the partial-filling level has not to exceed 85 % of the pipe diameter.
