Angled baffles are preferred in the agitation tank to control the swirling action; if the viscosity of the liquid to be mixed is about 200 poise. However, the baffle may be completely eliminated for mixing liquids having viscosity above ____________________ poise?
Correct answer: B
Explanation
At higher viscosities, the fluid's internal resistance is greater. This natural resistance helps dampen swirling motions, making baffles less necessary.
