The manifolds incorporate pressure tappings which allow the pressure drop across each pipe element to be measured using the four 500-0-500 mm water differential manometer bank. The manifolds also incorporate valved discharge points which allow the network to be configured to represent various distribution systems including a ring main and a long distribution system. The apparatus consists of a network of four coiled pipe elements and a differential manometer bank. The four pipe elements are located between a pair of large bore four branch valved manifolds which allow a number of series, parallel and series/parallel network configurations to be achieved. The Network of Pipes Apparatus has been designed as an additional experiment for use with Hydraulics Bench, which provides the basic service module for the pumping and volumetric measurement of the water supply.
Experimental Networks:
Single pipe
Series parallel network with 3 or 4 elements
Four pipes in series
Four pipes in parallel
Two pipes in series
Two pipes in parallel
A long distribution system with 1, 2, 3 or 4 discharge points
A 3 pipe series network with a parallel bypass
A distribution system with 2, 3, or 4 branches from a common manifold
A ring main distribution system with 1, 2, 3 or 4 discharge points
