Introduction
The PASCO SE-9076 Constant Velocity Tubes are simple devices that students can use
to generate velocity vs. time data for exercises to improve their graphing skills. The
plexiglass tubes contain colored, oil-based liquid of two different viscosities, and there
are three different lengths of liquid columns. A bubble of air trapped in each of the liquid
columns rises at a constant velocity that is determined by the viscosity of the liquid.
