# Propeller Turbine Mixer Design Calculator

## Wastewater Treatment - Mixing Equations

### Solving for power requirement (laminar flow). #### Inputs:

 mixing constant (k)
 fluid dynamic viscosity (μ) newton-second/meter^2dyne-second/centimeter^2pascal-secondkilogram/meter-secondpoisepound(f)-second/foot^2poundal-second/foot^2slug/foot-second
 revolution per second (n)

#### Conversions:

 mixing constant (k)= 0 = 0
 fluid dynamic viscosity (μ)= 0 = 0newton-second/meter^2
 revolution per second (n)= 0 = 0
 impeller diameter (D)= 0 = 0meter

#### Solution:

 power requirement (P)= NOT CALCULATED
