Which outcome limits heat exchanger effectiveness when cooling viscous oil?

💡 Explanation

A low Reynolds Number leads to laminar flow, because the momentum diffusivity dominates over the advective transport, therefore reducing mixing, thus limiting convective heat transfer, rather than anything contributing directly to conductive transfer alone which would have aided it.
