Zahn Viscosity Flow Cups

Use the included formula to convert seconds.

Zahn viscosity flow cups.

The principle operation of a zahn cup is resistance to flow. The only forces at work are gravity causing the flow and the hole size and gauge of the cup. The zahn cup s reading could be less sensitive than an automated viscometer employing a higher shear methodology. Five sizes are available for use on very thin oils to extremely heavy mixtures 20 1200 centipoise.

To determine viscosity dip the cup in a liquid until it is completely filled lift the cup out of the liquid and time how many seconds it takes for the liquid to drain out of the hole in the bottom.

Different cups have different shapes and hole sizes and because times too short or too long are unsuitable for any given viscosity there is an optimum cup with times in the 15 60s range.
