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

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

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

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