Orifice gravitational constant formula

\(\large{ G =  \frac{  \left (  \frac{ Q }{ C_d \; A_o } \right) ^2  }{ 2 \; h  }   }\)     (Orifice Gravitational Constant)

\(\large{ Q =  A_o \; C_d \; \sqrt { 2 \; G \; h } }\)

\(\large{ C_d =  \frac{ Q  }{ A_o \; \sqrt{ 2 \; G \; h }  }   }\) 

\(\large{ A_0 =  \frac{ Q  }{ C_d \; \sqrt{ 2 \; G \; h }  }   }\) 

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