This application was developed to provide simple on the spot calculations to both nonprofessionals and engineers working with projects involving the flow of fluids through pressurized pipes. The app uses the most accurate and widely accepted formulas for hydraulic analysis. Every formula has been employed with meticulous care and the functionality and accuracy of the program will be continually updated. It calculates head loss, flow rate, pipe diameter and pipe length by solving the Darcy-Weisbach and Colebrook-White equations from simple user inputs.
For Head Loss Calculation - input flow, diameter and length.
For Flow Rate Calculation - input hydraulic head, diameter and length.
For Pipe Diameter Calculation - input hydraulic head, flow and length.
For Pipe Length Calculation - input hydraulic head, flow and diameter.
The user can select from the following options:
1. Preferred units of measurement from metric or US customary units.
2. Pipe roughness coefficients from a wide range of pipe materials.
3. Resistance coefficients from commonly used pipe fittings and valves.
4. Fluid kinematic viscosities from a large range of fluids including fresh water and sea water at different temperatures.
Options 2, 3 and 4 can include user specified data.
NOTE: These options are only available with the paid version.
The main results (head loss, flow, diameter and length) from the selected calculation type are displayed at the top of the screen while all other important system data (friction loss, fittings loss, velocity head, flow velocity, flow type, Reynolds number and friction factor) is displayed at the bottom of the screen.
Note regarding critical flow or transitional flow zone at (2300 < Re < 4000):
It is well recognized that 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 inside this zone will be issued with a warning. The calculated results are average values but can vary significantly due to both friction factor and flow instability.
