Discharge from a sharp-edged orifice

Values for calculation

$d$ $\mathrm{mm}$
$d_o$ $\mathrm{mm}$

Calculation

Diameter ratio

$$β=\cfrac{d_o}{d}$$

Jet contraction ratio

$$λ=1+0.622\cdot\left(1-0.215\cdot β^2-0.785\cdot β^5\right)$$

Loss coefficient

$$ζ=0.0696\cdot\left(1-β^5\right)\cdot λ^2+λ^2$$

Discharge coefficient

$$μ=\cfrac{1}{\sqrt{ζ+1}}$$
