MEASURING VISCOSITY: ZAHN CUP<br />
(3 of 3)<br />
Paint flows through a hole in the cup bottom <br />
The cup is dipped into a liquid sample and then lifted out. The time the liquid takes to drain through the hole, at the point of break in the flow, is measured and converted into units of dynamic viscosity.
