When stirring is in laminar flow, why does an increase in Re lead to an increase in stirring power?
Thread Content
One question from the registered chemical engineering* question set: the relationship between the power coefficient Np for stirring and the stirring Reynolds number Re when the flow is in laminar condition. . . Re increases, Np decreases, but the stirring power increases. Why is this?
When the flow is in the laminar regime, since there is hardly any \"cylindrical swirling region,\" increasing the paddle width no longer results in an increase in power
I understood later. I’ve confused myself.
