HydroWiz Pipe Flow Hydraulics

About HydroWiz Pipe Flow Hydraulics Android App

HydroWiz was designed to be a versatile tool to help engineers find solutions to common pipe flow hydraulics problems allowing them to perform quick "what if?" calculations easily. It would also be useful to anyone working on simple water transfer projects involving pipes. The app solves the Darcy-Weisbach equation, the Colebrook-White equation and Bernoulli's equation to perform a range of hydraulic calculations on a single length of pipe between two known points.

NOTE - HydroWiz Lite is intended mainly for evaluation purposes. System options 2, 3 and 4 below are not available in this version. Download HydroWiz Pro to have all the features available.

MAIN CALCULATIONS
• ΔP Pressure Loss - calculates the pressure loss between P1 and P2.
• Q Flow Rate - calculates the volumetric flow rate in the pipe.
• D Internal Diameter - calculates the internal diameter of the pipe.
• L Pipe Length - calculates the pipe length for the given conditions.

OTHER CALCULATION RESULTS
• Elevation head.
• Head loss.
• Hydraulic head.

NOTE ON CRITICAL FLOW ZONE (2300 < Re < 4000)
It is well recognized that the flow within this narrow zone is unpredictable, unstable and not fully understood. The best practice is to design within the laminar flow or turbulent flow zones to avoid potential problems and uncertainty. Any calculation falling within this zone will be issued with a warning. The calculated results are interpolations and difficult to predict with accuracy due to both friction factor and flow instability.
