Water Flow Rate Through an Orifice formula |
||
| \( Q_w \;=\; 0.0865 \cdot C_d \cdot \left( \dfrac{d_o}{4.654} \right)^2 \cdot \sqrt{ \dfrac{ p_1 - p_2 }{ SG} } \) | ||
| Symbol | English | Metric |
| \( Q_w \) = Water Flow Rate | \(ft^3\;/\;se\) | \(m^3\;/\;s\) |
| \( C_d \) = Orifice Discharge Coefficient | \(dimensionless\) | \(dimensionless\) |
| \( d_o \) = Orifice Diameter | \( in \) | \( mm \) |
| \( p_1 \) = Primary Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p_2 \) = Secondary Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( SG \) = Water Specific Gravity | \(dimensionless\) | \(dimensionless\) |
