Falling Sphere Viscosimeter
Product Code: SUK-SCHOOL-SSLAB-K000139
Description & Specifications
Falling Sphere Viscosimeter
Technical Specification
The drag coefficient of spheres given the viscosity of the liquid. The
viscosity of liquids placed in the transparent tubes by measurement of
the terminal velocities of spheres in free fall in the liquids. Drag
coefficients for various geometric shapes, to be produced by the
students. By measuring the falling speed of a spherical ball in a
vertical tube filled with the fluid to study, it is possible to deduce
kinematic viscosity. Indeed, during the phase of the uniform rectilinear
motion, the various forces which apply to the ball ; gravity, the
pressure of Archimède and the force of trail related to viscous
friction, are in balance.
