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 tsPeripherial 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 watt4.8384 kw

6.488400845 HP

4 Power Lossa) Losses in mechanical seal (assumed) = 0.5 HPb) 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 HPTotal Power required for agitation = 7.824401 HP

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