FLUID MECHANICS LAB EQUIPMENTS 1. HYDRAULIC BENCH DESCRIPTION The hydraulics bench consists of a moulded plastic sump tank which supports GRP bench top incorporating a flow channel and volumetric measuring tank. A self-priming centrifugal pump and draws water from the sump tank and delivers to a quick release hose connector in the flow channel via a panel mounted control valve. Special purpose terminations may be connected to the pump supply by unscrewing the hose connector. No hand tools are required for either of these operations. A drain valve is incorporated in the end wall of the sump tank to facilitate emptying. Electrical supply to the pump motor is via a switch and RCD mounted in the recess on the front of the bench. The moulded bench top incorporates an open flow channel with ridges at either side to support the accessory on test. In addition to the hose connector the channel incorporates a pair of wall slots and a weir carrier for use with accessory F1-13. Water discharging from the accessory on test is collected in the volumetric measuring tank. This tank is stepped to accommodate low or high flow rates and incorporates a stilling baffle to reduce turbulence. A remote sight tube and scale, is connected to a tapping in the base of the volumetric tank and gives an instantaneous indication of water level. A dump valve in the base of the volumetric tank is operated by a remote actuator. Lifting the actuator opens the dump valve allowing the water to return to the sump for recycling. When lifted, a twist of 90° at the actuator will retain the dump valve in the open position. An overflow adjacent to the sump returns water to the sump in the event of incorrect use. A measuring cylinder is provided for measurement of very small flow rates.

IMPACT OF A JET DESCRIPTION Fluid mechanics has developed as an analytical discipline from the application of the classical laws of statics, dynamics and thermodynamics, to situations in which fluids can be treated as continuous media. The particular laws involved are those of the conservation of mass, energy and momentum and, in each application, these laws may be simplified in an attempt to describe quantitatively the behaviour of the fluid. The hydraulics bench service module, F1-10, provides the necessary facilities to support a comprehensive range of hydraulic models each of which is designed to demonstrate a particular aspect of hydraulic theory. The specific hydraulic model that we are concerned with for this experiment is the Impact of Jet Apparatus, F1-16. This consists of clear acrylic test cylinder, into which water is fed vertically through a nozzle. The water strikes a target mounted on a stem. A weight pan mounted at the top of the stem allows the force of the water to be counterbalanced by applied masses. A full description of the apparatus is given later in these texts.
