AGITATOR DESIGN

Vessel MOC SS304

Liquid Density p 1200 kg/m3
Liquid Viscosity µ 50 CP
0.05 N.s/m2
Required Rotation N 200 RPM
3.3333333 RPS

Power Number Np 1.4 (as per graph)

Curve consider 6

Nre 28800

HP CALCULATION

1 Reynolds number for agitated liquids Nre = ( Da² x N x p / µ ) 28800

Nre is in between 10 & 10000. Hence fluid is Transition Flow.

 2 Impeller Tip speed ts
Peripherial Speed of an impeller = π x Da x N 6.283185 m/s

3 Power Required for Baffled Tank P = Np x p x N^3 x Da^5 4838.4 watt

4.8384 kw
6.488400845 HP

4 Power Loss
a) Losses in mechanical seal (assumed) = 0.5 HP
b) Drive Losses
i) Gear box is used = 0.836 HP
ii) Gear box is not used = 0.209 HP

Approximately power loss in the agitation = 1.336 HP

Total Power required for agitation = 7.824401 HP

Hence this power is rounded to the standard electric motor rating i.e 8 HP
