The Reynolds number for an agitator can be calculated with the following formula : N Re = D 2.N.ρ / μ. With : N Re = impeller Reynolds number (-) D = impeller diameter (m) N = agitator speed (r/s) ρ = liquid density (kg/m3) μ = liquid viscosity (Pa.s)
If we assume that the tangential liquid velocity is some fraction k, of the blade-tip velocity then: Vu2 = tangential component velocity of the liquid leaving the blade tip. u2 = velocity of the impeller blade tip. D = diameter of the impeller, feet. N = rotational speed of the impeller.
14 Ιουν 2024 · The Agitator Tip Speed Calculator calculates the tip speed of an agitator, which is the speed at the edge of the agitator blade as it rotates. This speed is crucial for understanding the shear and mixing efficiency within a tank or reactor and for ensuring that the agitator operates within safe mechanical limits to prevent wear and tear.
To calculate the tip speed of an agitator, use the formula Tip Speed = π * D * n or Tip Speed = (π * D * N) / 60, where D represents the diameter of the blade in meters, n (or N) indicates the rotational speed of the blade in revolutions per minute (rpm), and π (pi) is approximately 3.14159.
2 Δεκ 2023 · In the context of impellers or agitators, tip speed is calculated by multiplying the rotational speed of the device (in revolutions per minute or RPM) by the radius or distance from the center of rotation to the outermost edge of the blades. The formula for tip speed (TS) is: TS=2 X pi ×Rotational Speed× Radius. TS=2π × Rotational Speed × Radius.
