| \(\large{ Q_w = 0.0865 \; C_d \left( \frac{d_o}{4.654 } \right)^2 \; \sqrt { \frac{ p_1 \;-\; p_2 }{ SG } } }\) | ||
| Symbol | English | Metric |
| \(\large{ Q_w }\) = water flow rate | \(\large{\frac{ft^3}{sec}}\) | \(\large{\frac{m^3}{s}}\) |
| \(\large{ d_o }\) = diameter of orifice | \(\large{ in }\) | \(\large{ mm }\) |
| \(\large{ C_d }\) = orifice discharge coefficient | \(\large{dimensionless}\) | |
| \(\large{ p_1 }\) = primary pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_2 }\) = secondary pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ SG }\) = specific gravity of water | \(\large{dimensionless}\) | |
