Conclusions 1. When ΓΓ 〉 0.8 (Re〉1000, Fr≥2.5, and R/d≤6.7) the air core of a vortex penetrates a drain and causes a decrease of the discharge coefficient. 2. When Fr≥2.5 and Re〉30,000 the relative discharge coefficient does not depend on the Froude and Reynolds numbers. 3. In the region ΓΓ = 0.8−2.1 (when Re〉30,000, Fr≥2.5, and R/d=2.5–6.7) the dependence of the realtive discharge coefficient on the reduced circulation is linear. 4. For each value of R/d when Re〉30,000 there is a limiting value of ΓΓ max, above which the discharge coefficient remains practically constant.
