INSTRUCTIONAL
CAPABILITIES
The provision of practical instruction exercises
demonstrating the principles of fluid mechanics, in particular:
Understanding the
properties of fluids:

the density, specific gravity and viscosity of different liquids
§ observing
the effects of capillarity
Understanding
the effects of static pressure:
§ demonstrating
that the free surface of a static liquid is horizontal
§ studying
the effect of flow on a free surface
§ measuring
changes in liquid level
§ studying
the relationship between intensity of liquid pressure and depths
§ determining
the position of the centre of pressure on a plane surface
Studying the operation and application of pressure gauges
and manometers:
§ using a direct reading Mercury barometer
(Mercury not supplied)
§ measuring air and water pressure using manometers
§ comparing results obtained from various
devices
§ calibrating a Bourdon-type pressure gauge
using a deadweight pressure gauge calibrator
Investigating the buoyancy force and
stability of floating bodies:
§ verifying Archimedes' principle
§ determining metacentric height
