Re: Can you help me size the motor for a mixing tank?11 June 2012 at 1:29pm
This question appears to contain some information that can be misinterpreted because of language differences. The following assumptions are being made concerning the information provided:
Tank diameter = 3 meters
Tank height = 3 meters
Shaft diameter = 0.1 meters
Density of milk of lime: rho = 1042 kg/m^3
Impeller diameter: D = 1.4 meters
Rotational speed = 40 rpm, N = 0.667 revolutions/second [rps]
Number of blades on the impeller = 6
Blade angle = 60/10 from horizontal or arctan(6) = 80 degrees from horizontal
Estimated power number Np = 4.7
The answers by this expert are based on the best available interpretation of the information provided. The consequences of the application of this information are the responsibility of the user. If clarification is needed, please submit a further question.
I have a tank with these dimensions: diameter and height 3 meters. I want to do a vertical arrangement of mixing in this tank. Material of this tank is milk of lime, which has a density of 1.042kg/m3, diameter of stirring shaft is 0.1 meter and it has 6nor. of arm of length 1.4 meter. Mixing rpm is 40. Arm is made by m.s. angle of 60/10 mm and shaft is solid m.s. What size should the motor be?
Have an insight or suggestion?
