Orifice Flow Rate

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

Orifice Flow Rate Formula

\(\large{ Q =  C_d A_o \sqrt { 2Gh } }\)          

Where:

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

\(\large{ A_o }\) = orifice area

\(\large{ C_d }\) = discharge coefficient

\(\large{ G }\) = gravitational constant

\(\large{ h }\) = center line head

Solve for:

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

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