F9092 – Fluid Properties & Hydrostatics Bench

The Armfield Fluid Properties and Hydrostatics Bench is designed to demonstrate the properties of fluids and their behaviour under hydrostatic conditions (fluid at rest).

Description

The Armfield Fluid Properties and Hydrostatics Bench is designed to demonstrate the properties of fluids and their behaviour under hydrostatic conditions (fluid at rest).

This enables students to develop an understanding and knowledge of a wide range of fundamental principles and techniques, before studying fluids in motion.

The equipment is mounted on a steel-framed bench fitted with castors. A variety of measuring devices is incorporated, either fastened to the back of the bench or free-standing.

Water is stored in a polythene tank situated on the lower shelf of the bench.

The water can be transferred by two positive displacement hand pumps, either to an elevated open storage tank connected to a number of glass tubes for free surface studies, or to a plastic sink recessed into the working surface so that benchtop experiments may be conducted without spillage.

All excess water is returned to the storage tank via the sink drain.

The following experimental apparatus is included:

  • Universal hydrometer and hydrometer jars
  • Falling sphere viscometers
  • Free surface tubes
  • Hook and point gauge
  • Mercury barometer (mercury not supplied)
  • Bourdon gauge
  • U-tube manometers
  • Deadweight pressure gauge calibrator and weights
  • Hydrostatic pressure apparatus
  • Pascal’s apparatus
  • Parallel plate capillary apparatus
  • Capillary tube apparatus
  • Lever balance with displacement vessel, bucket and cylinder
  • Metacentric height apparatus
  • Measuring cylinder
  • Thermometer
  • Air pump
  • 600ml beaker
  • Stop clock

H12-8: Basic Portable Pressure Meter

Consequent to its hazardous nature many technicians prefer not to use mercury or its use may be prohibited in the laboratory. In any case Armfield is unable to include it in the supply with the purchase of mercury manometers due to shipping restrictions. With this in mind Armfield offers a handheld, portable, battery-operated pressure meter (H12-8), which is capable of measuring pressures of air or water from 0-2,000mBar (0-1,500mm Hg).
