Question

Coefficient of discharge of orifice meter formula

Answer 1

Symbols and units for discharge coefficient equations: Ao=orifice area (m2), Ap=pipe area (m2), d=orifice diameter (m), D=pipe inside diameter (m), P1-P2=differential pressure (N/m2), P1-P3=non-recoverable pressure difference (N/m2), Q=flow rate (m3/s), Vo=velocity through orifice (m/s), Vp=velocity in pipe (m/s), ρ.
