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. 600
- A. 300
- B. 600
- C. 1000
- D. 1500
Explanation
At about 200 poise, angled baffles reduce vortex formation without excessively disturbing the viscous liquid. Above roughly 600 poise, the liquid is so viscous that swirling is minimal and baffles can be omitted.
