# Venturi Meter Design Equations Calculator

## Fluid Mechanics Hydraulics Formulas

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.

#### Conversions:

 Area 1= 0 = 0meter^2
 Area 2= 0 = 0meter^2
 Pressure 1= 0 = 0pascal
 Pressure 2= 0 = 0pascal
 Density= 0 = 0kilogram/meter^3

#### Solution:

 Flow rate (Q)= NOT CALCULATED
