FLUID PROPERTIES (HYDRAULIC BENCH ACCESSORIES)

This apparatus provides an introduction to the fundamental properties of liquids that affect their behavior in practical applications.A clear understanding about the physical properties of fluids is essential before studying the behavior 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 with circular spirit level and adjustable feet for leveling. 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.
