Orifice Flow Rate

Written by Jerry Ratzlaff on . Posted in Flow Instrument

Orifice flow rate is the amount of fluid that flows in a given time.

formula

\(Q =  C_d A_o \sqrt { 2GH    }   \) 

Where:

\(Q\) = flow rate

\(C_d\) = discharge coefficient

\(A_o\) = orifice area

\(G\) = gravitational constant

\(H\) = center line head

Solve for:

\(G =  \frac   {      \left (  \frac  { Q  }  {  C_d A_o  } \right) ^2     }  { 2H  }   \)

\(H =  \frac   {      \left (  \frac  { Q  }  {  C_d A_o  } \right) ^2     }  { 2G  }   \)
