Venturi Meter Flow Rate

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Venturi meter flow rate measures the velocity of a fluid through a pipe.

formula

\(Q =   A_2   \sqrt { \frac {     {2 \left ( p_1 \; - \; p_2 \right)}     }     { \rho \left(   1\; - \;    \left( \frac {A_2} {A_1}   \right) ^2       \right) }     } \)

Where:

\(Q\) = flow rate

\(A_1\) = area 1

\(A_2\) = area 2

\(p_1\) = pressure 1

\(p_2\) = pressure 2

\(\rho\) = density
