Venturi Meter Flow Rate

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

Venturi Meter Flow Rate Formula

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

Where:

\(\large{ Q }\) = flow rate

\(\large{ A_1 }\) = area 1

\(\large{ A_2 }\) = area 2

\(\large{ p_1 }\) = pressure 1

\(\large{ p_2 }\) = pressure 2

\(\large{ \rho }\) = density
