• Description

Key Features
• Falling sphere viscometer for experiments in
drag coefficient and fluid viscosity
• Two transparent glass tubes allows students
to simultaneously compare different fluids,
without requiring draining and refilling
• Safe, low-voltage backlighting so students
can see the falling test spheres through dark
fluids
• Includes test spheres of different sizes and
densities to help match a range of test fluids
• Unique valve exit system allows students to
recover test spheres with minimal fluid loss
• Includes stopwatch and timing marks for
accurate results
Learning Outcomes
• Determination of the viscosity of different
fluids
• Determination of the drag coefficient of
various spheres
• Visual demonstration of viscosity,
simultaneously on two different fluids
