## What is FlowCalculator?

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 performances. You can choose between the metric and the imperial system of units.

## Key features

- Volumetric flow calculation
- 3D graphic value adjustment

### 5/5 — Einfach nützlich

*2024-09-01, version 1.6.1*

Ist einfach zu bedienen und gibt schnell eine Antwort zur Dimensionierung einer Rohrleitung

### 3/5 — Display goes to Half Screen

*2024-08-08, version 1.6.1*

Great app - the calls still work but now only displays a half screen of results and it will not move.  Hopefully this is a glitch that the next upgrade will fix.

### 1/5 — Funktioniert nicht mehr

*2024-04-27, version 1.6.1*

Seit neulich wird das Display mit einer Meldung abgedeckt und die Berechnung wird nach unten verschoben, und die Steuerung nicht mehr möglich ist. Somit ist die App nicht mehr brauchbar. Schade!

### 4/5 — Thanks

*2014-02-26, version 1.1.2*

Thanks a lot for your efforts for this useful app.

### 5/5 — Einfach genial

*2013-09-25, version 1.0.0*

Ich habe lange nach einer schnellen und einfachen Lösung zur Berechnung der Volumina gesucht und jetzt gefunden
Einfach genial
