Weve done viscosity experiments before by letting the liquids flow down an inclined board. To make your observations simply drop the marble into the fluid and using the stopwatch try to time the marble as it crosses each of the marks (i.e. Your email address will not be published. The free A fluid with a large viscosity resists motion because its molecular makeup gives it a lot of internal friction. The speed at which a ball sinks to the ground in a fluid is directly dependent on the viscosity of the fluid. >> /ExtGState << Glycerin 3. /a0 << endstream
