Witryna2 lut 2011 · Mass transfer processes in agitated vessels are almost invariably turbulent, with mixing Reynolds numbers above 10 4 in the uniform ungassed Power number regime (Re = ND 2 ρ/η, where D and N are the impeller diameter and speed, and ρ and η are the liquid density and viscosity, respectively, (see Agitation Devices).Energy … WitrynaUsually, electrical power is used to drive impellers in stirred tanks. For a given stirred speed, the power required depends on the resistance offered by the fluid to rotation … songs about keeping secrets
How do I calculate impeller speed of a bioreactor from impeller power ...
Witryna27 kwi 2024 · Power, P = 10.54 / 0.75 = 14.05 HP ~15 HP, Torque, 𝒯 = P x 75 / (2𝞹 x N) = 15 x 75 / (2 x 3.141 x (60/60)) = 179.08 Kg-m, Maximum Torque, 𝒯m = 2.5 x 𝒯 = 2.5 x 179.08 = 447.7 Kg-m, Zp = 𝒯m / Fs = 447.7 x 100 / 550 = 0.814 x 100 = 81.4 cm3, Shaft dia, Ds = (16 x Zp / 𝞹)^0.33 = (16 x 81.4 / 3.141)^0.33 = 7.4569 ~7.5 cms, Witryna7 lut 1983 · The impeller is keyed to the shaft and rotates at the motor operating RPM. Centrifugal force causes the fluid to move from the eye of the impeller outward. … Witryna11 wrz 2024 · To calculate the new flow rate of a pump from an increase or decrease in impeller diameter, the following formula and calculation can be used.
