Orifice gravitational constant formula

\( G \;=\; ( Q \;/\; C_d \; A_o )^2  \;/\; 2 \; h_c  \)     (Orifice Gravitational Constant)

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

\( C_d \;=\; Q  \;/\; A_o \; \sqrt{ 2 \; G \; h_c } \) 

\( A_0 \;=\; Q  \;/\; C_d \; \sqrt{ 2 \; G \; h_c }  \) 

\( h_c \;=\; ( Q \;/\; A_o \; C_d )^2  \;/\;  2  \; G  \) 

Symbol English Metric
\(G \) = Orifice Gravitational Constant  \(lbf-ft^2 \;/\; lbm^2\)  \(N - m^2 \;/\; kg^2\)
\( Q \) = Orifice Flow Rate \(ft^3 \;/\; sec\) \(m^3 \;/\; s\)
\( C_d  \) = Orifice Discharge Coefficient \( dimensionless \) \( dimensionless \)
\( A_o \) = Orifice Area \( in^2 \) \( mm^2 \)
\( h_c \) = Orifice Center of Head \( in \) \( mm \)
