Pressure Drop Calc app for iPhone and iPad

This is an indispensable tool for the working professional or engineering student.

All you have to do is enter the fluid flow rate, pipe inside diameter, fluid density, fluid viscosity, pipe roughness factor (not the relative roughness but the pipe material roughness) along with the equivalent length in either pump runs or a combination of piping plus valves and fittings. When you click the calculate button it will return the Reynolds number, Fanning friction factor, pressure drop and fluid velocity in the pipe. The Fanning friction factor is calculated using the Churchill equation which is valid for the laminar, transition and turbulent range. The default roughness factor is for commercial steel.
