$l$ $\mathrm{mm}$

Calculation

Diameter ratio

$$β=\cfrac{d_1}{d_2}$$

$$0.1< β^2< 0.9$$

Coefficient $ φ_0 $

$$φ_0=1.01-0.624\cdot\cfrac{l}{d_1}+0.3\cdot\left(\cfrac{l}{d_1}\right)^2-0.074\cdot\left(\cfrac{l}{d_1}\right)^3+0.007\cdot\left(\cfrac{l}{d_1}\right)^4$$

Loss coefficient

$$ζ=φ_0\cdot\left(1.43-1.3\cdotβ^2\right)\cdot\left(1-β^2\right)^2$$

Discharge coefficient

$$μ=\cfrac{1}{\sqrt{ζ+1}}$$
