The coefficient of velocity for an orifice is
1
\( {{\rm{C}}_{\rm{v}}}{\rm{\;}} = {\rm{\;}}\sqrt {\frac{{4{{\rm{x}}^2}}}{{{\rm{yH}}}}} \)
2
\({{\rm{C}}_{\rm{v}}}{\rm{\;}} = {\rm{\;}}\frac{{\rm{x}}}{{\sqrt {4{\rm{yH}}} }}\)
3
\({{\rm{C}}_{\rm{v}}}{\rm{\;}} = {\rm{\;}}\sqrt {\frac{{{{\rm{x}}^2}}}{{4{\rm{y}}}}} \)
4
\({{\rm{C}}_{\rm{v}}}{\rm{\;}} = {\rm{\;}}\frac{{\sqrt {4{\rm{yH}}} }}{{3{\rm{x}}}}\)
