Power Number
Power number is proportional to { (drag force) / (inertial force) } and is used in momentum transfer in general and power consumption by agitators, fans, pumps, etc. calculations in particular. It is normally defined in the following form :
Where: |
D |
= |
Characteristic length |
gc |
= |
Dimensional constant |
N |
= |
Rate of rotation |
P |
= |
Power |
rho |
= |
Density |
