The set up is a self-contained, water recirculation unit provided with a top tray, sump tank and a measuring tank. Drain valve and over-flow are provided on the sump tank. A centrifugal pump is fitted tor water circulation. Flow control valve and bypass valve is fitted in water line to conduct the experiment at different flow rates. Flow rate of water is measured with the help of measuring tank and stop watch. Measuring tank is provided to measure the discharge. Drain valve is provided in the measuring tank to empty water in sump tank after measuring discharge. Separate level indicator and scale is provided to read the level of water in the measuring tank. RANGE OF EXPERIMENTS: Following experimenta can be carried out with common basic table with separate experimental setup (supplied at extra cost>, which can be connected to Hydraulic Bench with flexible pipe. Bernoulli's Theorem Apparatus Orifice and Mouth Piece Apparatus Flow measurement by Venturimeter and Orificemeter Losses due to Friction in Pipe Lines Losses in Pipe fitting and Pipe Bends Reynold's Number study Flow over notches Impact of Jet on Vanes Pi tot Static Tube Salient Features Top Tray : 1060 mm x 650 mm.

Hydraulic bench is a very useful apparatus in hydraulics and fluid mechanics. It is involved in majority of experiments to be conducted e.g. To find the value of the co-efficient of velocity Cv , coefficient of discharge Cd , to study the characteristics of flow over notches, to find metacentric height, to find head losses through pipes, to verify Bernoulli s theorem etc. Parts of Hydraulic Bench Machine: Its parts are given below: Centrifugal pump It draws water from sump tank and supplies it for performing experiments. Sump Tank It stores water for Hydraulic bench. It is located in the bottom portion of Hydraulic bench. Water from here is transported to other parts by using a pump. It has a capacity of 160 liters. Vertical pipe It supplies water to the upper part of hydraulic bench from sump tank through a pump. Control valve It is used to regulate the flow in the pipe i.e. to increase or decrease the inflow of water in the hydraulic bench.Parts of Hydraulic Bench Connecter With the help of this we can attach accessories with the hydraulic bench. Special purpose terminations may be connected to the pump supply by unscrewing connecter, no hand tools are required for doing so. It is located in the channel. Channel It is used in number of experiments It provides passage for water for different experiments. Drain valve It is used for emptying sump tank. Side channels They are the upper sides of the channel. They are used to attach accessories on test. Volumetric tank It stores water coming from channel. This tank is stepped to accommodate low or high flow rates. It has a capacity of 46 lits. Stilling baffle It decreases the turbulence of water coming from channel. It is located in the volumetric tank. Scale & Tapping A sight tube and scale is connected to a tapping in the base of the volumetric tank and gives an instantaneous indication of water level. Dump valve It is at the base of the volumetric tank. Opening the dump valve allows the entrained water to return to the sump tank for recycling. It is used for emptying volumetric tank. It is located in the bottom of the volumetric tank. Actuator Dump valve is operated by a remote actuator, lifting actuator opens the dump valve, when it is given a turn of 90 it will turn the dump valve in the open position. Over flow It is an opening in the upper portion of the volumetric tank. It sends the water level above 46 lits to the sump tank. Measuring cylinder A measuring cylinder is provided for measuring of very small flow rate. The cylinder is stored in the compartment housing the pump. Starter It on / off the hydraulic bench. |
