Orifice and Mouthpiece Apparatus (SMT-FM-11A)

This equipment allows a user to study and visualize the profile of a water jet. This apparatus allows students to measure the Decrease in flow, contraction of stream and energy losses. Additionally, the contraction coefficient can be determined as a characteristic for different contours. The experimental unit includes a Stainless-steel tank, point gauges, water storage tank, a pump, flow control valve and transparent interchangeable orifices and mouth pieces to facilitate the investigation of various openings. Two orifice and two mouthpieces with different diameters are provided along with the unit. To visualize the trajectory, the issued water jet is measured via a point gauge that consists of movable steel rods with measuring scale. The rods are positioned depending on the profile of the water jet. The constant head tank contains an adjustable overflow and a scale. In this way, a precise adjustment and accurate reading of the fill level are possible. The experimental unit is standalone and I can run independently without hydraulic bench.
