Calculation examples for agitation systems
Mixing pasty products - Agitator performance

The power required to drive a helical ribbon type agitator (N = 100 rpm) with the following main geometrical characteristics is calculated:

The mobile is placed in a tank 0.346 m in diameter t, containing a viscous Newtonian liquid (V = 30 L) with density ρ = 1,400 kg/m ³ and viscosity µ = 40 Pa.s.

The previously determined constants K _P and K _s are equal to 315 and 32 respectively....
