FlowCalculator allows the fast and easy calculation of the volumetric flow in dependence of the pipe diameter or the flow velocity. Change the values in the three-dimensional graphic representation by tapping on the screen with one or two fingers or tap on the corresponding value to also change it numerically. In addition to this, an independent unit converter is integrated in the app which allows the conversion of e. g. areas, dimensions, lengths, temperatures, frequencies, pressures or perfor
