AioFlo is a powerful and user-friendly Windows application that performs pipe sizing, flow rate and pressure drop calculations for liquids and isothermal gases. Information for a wide range of fittings such as entrances, exits, bends, tees, reducers, valves and orifices is built in. The resistance coefficients (K-values) are calculated using the Hooper and Darby methods for the laminar and turbulent flow regimes. Friction factors are automatically calculated (using the Churchill equation) for all flow regimes. Changes in elevation from inlet to outlet are taken into account. The pressure drop for liquids is also expressed in terms of head of flowing fluid for pump sizing.

The program includes data tables for pipe size and roughness. Units handling is unparalleled, allowing the units for any individual property to be set independently, or in predefined sets (US Customary, SI Units and Metric Units) and in user-defined sets of mixed units. Viscosities can be specified in dynamic or kinematic units.

Flow rates can be specified and calculated in mass or volumetric terms. The calculation results can be saved to disk, and printed to neat single page reports. AioFlo also includes the facility to perform preliminary sizing and capacity calculations based on typical velocities when insufficient data is available to perform a detailed hydraulic calculation.

The AioFlo program is totally self-contained and has no dependency on any frameworks, run-time libraries or DLLs.
