The hydraulic bench represents a service unit for a wide variety of complementary accessories that enable to perform several experiments of fluid mechanics. The upper part of the bench consists of a work top equipped with an open channel above which the accessories are placed, and of two tanks that enable to carry out some volumetric measurements of the flow rate by using a level gauge. The bottom of the volumetric tank is equipped with a valve in
order to drain the water in the supply tank. The water is drawn to the top of the bench by a centrifugal pump, whereas the flow rate is adjusted through a control valve and measured with a variable area flowmeter. The variable-area flowmeter enables to compare the flow rate read on the instrument with the flow rate measured through the measuring tanks.
