Description of Hydrostatics Bench:
Hydrostatics Bench is styled to be a matching unit to Hydraulics Bench, which provides a range of hydro dynamic experiments. The unit is self-contained and independent of all laboratory services. The bench consists of a steel-framed unit, mounted on castors, and containing a high quality fibreglass work surface, a steel backboard and a storage cupboard and shelf under the work surface. The working surface is recessed and supplied with a drain point. A number of the individual experiments are permanently mounted on the backboard, whilst the remaining items are conveniently stored in the cupboard along with the triple beam balance. The optional barometer, consists of siphon type barometer mounted on a wooden backboard supplied complete with mounting brackets for attaching to the frame of the Hydrostatics Bench.
