The present set-up is designed to study the flow through different orifices and mouthpieces. It consists of an inlet tank provided with diffuser and provision for fitting Orifice or Mouthpiece at the outlet which can be easily attached or detached without need of any tool. An overflow arrangement is done to vary head and keep it constant at desired level to conduct varieties of experiments. A pointer gauge for measuring ordinates of Jet is fitted on flow channel. Centrifugal pump is used to re-circulate the water from sump tank to the inlet tank and test section and is return back to the sump tank. Flow diverter is provided to divert the flow either to measuring tank or sump tank. Constant head condition is maintained in the inlet tank. Experiments can be conducted on different flow rates and measured with the help of measuring tank with piezometer and stopwatch.
