# vibrator force calculation formula

The flotation velocity can be calculated with the help of the formula above. The following average values apply at an ambient temperature of about 35 °C: d = 3 µm = 3 x 10 –6 m (ρ p – ρ l) = (980 – 1 028) = – 48 kg/m 3 h = 1.42 cP (centipoise) = 1.42 x 10 –3 kg/m, s. Substituting these values in the formula:
