Description

A clear understanding about the physical properties of fluids is essential before studying the behaviour of fluids in static or dynamic applications.

This apparatus introduces students to the following properties of fluids:

Density and relative density (specific gravity)
Viscosity
Capillarity – capillary elevation between flat plates and in circular tubes
Buoyancy (Archimedes principle)
Atmospheric pressure

The apparatus consists of a collection of components that demonstrate individual fluid properties. The components are stored on a common support frame manufactured from PVC with circular spirit level and adjustable feet for levelling. The apparatus is designed to stand on a suitable bench top where some of the components can be operated independent from the support frame.

A freestanding dual scale lever balance is also supplied to support several of the demonstrations.
