The free discharge apparatus (FM – 012) is a bench top kit, which designed to illustrate orifices with different inlet and outlet diameters. The unit also identify the determination of the diameter and velocity of the outlet jet.
- The educational unit demonstrates the pressure losses in the vertical flows from tanks, the unit also determines the contraction coefficient for different inlet and outlet contours and diameters.
- The experimental unit includes a transparent tank with an adjustable overflow, a measuring device as well as a Pitot tube and twin tube manometers.
- The transparent tank provides an excellent observation of the experiments, it has an orifice fitted in the base.
- The educational unit also includes an interchangeable insert that is installed in the tank’s water outlet to facilitate the investigation of various openings.
- The unit is supplied with five inserts with different diameters, inlet contours and outlet contours to perform different experiments.
- The issued water jet diameter is measured using the measuring device and the Pitot tube detects the total pressure of the flow.
- The pressure difference that is read on the manometer, is used to determine the jet velocity.
- The tank is fitted with an adjustable overflow and a measuring point for static pressure. In this way, the level can be precisely adjusted and read on the manometer.
- The experimental unit is positioned easily and securely on the work surface of the main hydraulic unit base module.
- The water is supplied and the flow rate measured by main hydraulic unit.
