# Is there a conclusive correlation between viscosity and surface tension?

I'm working on a project and I need to know if the viscosity effects on the surface tension or not?

• No, they arise from totally different mechanisms. It's possible you'll find specific systems where viscosity and surface tension are correlated, but in general there is no correlation. – John Rennie Nov 27 '15 at 11:22

$\mathbf{\text{Viscosity}}$: it arises from cohesive forces between the (similar) molecules & the momentum exchange between the adjacent/consecutive layers of a fluid.
$\mathbf{\text{Surface tension}}$: it arises only from the cohesive forces between the similar molecules at the free surface & the molecules inside of a fluid
