Venturi Meter Design Equations Formulas Calculator
Fluid Mechanics Hydraulics
The venturi meter device measures the flow rate or velocity of a fluid through a pipe. The equation is based on the Bernoulli equation, conservation of energy, and the
continuity equation.
Solving For Flow Rate
Inputs:
Conversions:
| Area 1 | = | 0 | | = | 0 | meter^2 |
| Area 2 | = | 0 | | = | 0 | meter^2 |
| Pressure 1 | = | 0 | | = | 0 | pascal |
| Pressure 2 | = | 0 | | = | 0 | pascal |
