Q. What is the difference between a stalagmometer and a viscometer?

Answer

Here is the difference:A tool for using the stalagmometric technique to study surface tension. A stalagmometer, a glass device for measuring surface tension, was commonly used to quantify alcohol content.A device for determining the thickness of a fluid. The thickness of a liquid can be measured with a device called a viscometer (or viscosimeter). A rheometer is used to measure the viscosity of fluids whose properties change under different flow conditions.Rheometers are a subset of viscometers, therefore it makes sense to think of them in this way. For laminar flow to occur, the Reynolds number of the flow conditions must be very tiny.
