Motor Sizing
Motor Sizing
(OP)
We have an idea in mind for a mixer/paddle that would be inserted in a process stream. Any ideas on sizing the motor to drive it? Any ideas on figuring the hydraulic loads or drag? We're at the very beginning of this.

Is this line of reasoning right? Am I overlooking anything else?

A general equation expressing the power requirements for paddles is:
Hp = [( CD *k* A ) / 66,000 ] ( B /60 )**3* d**3* n**3
your hp is off
Remember losses in the gear box and chain drive.
The mixing speed is very fast

What are CD, k, A, B, d and n?

What are you mixing and have you done any shear rate evaluation of fluid.
