is there relation for it?
thanks for your reply

RE: impeller
for reply,
can you address practical formulas for mixing application?
thanks
RE: impeller
The basic relationship between Power (P), speed (N), diameter (D) and fluid density (ρ)is:
P ∝ N^3.D^5.ρ
Specific calculations need input from the suppliers with regards to the performance of the particular impeller type selected.

NB
RE: impeller
P = N*p*N3D5/1000
where: P = power dissipation, kW
N = power number, dimensionless
p = fluid density at conditions, kg/m3
N = impeller rotational speed, revis
D = impeller diameter, m
