The role of Baffles is to improve mixing and remove stratification during agitation. Correct Answer True

During the process of agitation the baffles, which are one of the mechanical agitation devices used, remove stratification in the radial direction and improve mixing performance. A typical agitator vessel setup consists of 4 baffles and 1 impeller.

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 viscoisty above __________ poise.
Assertion (A) Each role must have enough stressers which may help the role occupant to stretch himself/herself to meet the challenge. In the role, where the scope is limited to routine work, the role occupants do not perceive any challenge.
Reason (R) While every role has some routine elements, challenge can also be incorporated into every role. However, the challenge should not exceed an optimal limit, otherwise it may produce dysfunctional stress, resulting in poor performance or damage to the health of the employee in the long-run.
