Venturi Tube Flow Rate

Venturi Tube Flow Rate Formula

(Eq. 1)  \(\large{ Q = C_v A \sqrt {2  g  h_l}  }\)         

(Eq. 2)  \(\large{ Q = C_v A \sqrt {  \frac { 2 p_l} {\rho}  }  }\)         

Where:

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

\(\large{ A }\) = cross section area

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

\(\large{ C_v }\) = flow coefficient

\(\large{ g }\) = gravitational acceleration

\(\large{ h_l }\) = head loss

\(\large{ p_l }\) = pressure loss
