The apparatus is mounted in a self contained modular frame and comprises two similar dual speed centrifugal pumps interconnected by an arrangement of pipes and valves which can be arranged so that the performance of a single pump, two pumps in series or two pumps in parallel can be determined. Delivery pressure is measured on a Bourdon gauge and flow rate is measured using the H1 or H1d Hydraulic Bench.</P> <H5><FONT COLOR="#800040">Supporting Teaching Material </FONT></H5> <P>The manual provides all relevant theory, experimental procedures and sets of typical results.</P> <H5><FONT COLOR="#800040">Range of Experiments </FONT></H5> <P>1.

The interconnecting pipe and valve assembly allows the performance of a single pump, two pumps in series or two pumps in parallel, to be determined. The unit has been designed to be used with a Hydraulics Bench and is floor standing alongside the bench when in use. Requires a 220/240V 50/60Hz single phase or a 220/240V 50/60Hz two phase supply, total power consumption being 250W max. The overall size of the unit should be no more than 500 x 500 x 700m.</P> <P>Equipment to be supplied with a two year parts and labour warranty. </BODY> </HTML>
