Description

This ESOLS’s Apparatus includes a transparent PPI tank, a measuring device as well as a Pitot
tube and twin tube manometers. An interchangeable mouthpiece is installed in the tank’s
water outlet to facilitate the investigation of various openings. Five mouthpieces with
different diameters, inlet contours and outlet contours are provided along with the unit.
Pressure losses in the flow from tanks are essentially the result of two processes: the jet
deflection upon entry into the opening and the wall friction in the opening. As a result of the
pressure losses the real discharge is smaller than the theoretical flow rate. SMT-FM-05
determines these losses at different flow rates. Different diameters as well as inlet and outlet
contours of the openings can be studied. Additionally, the contraction coefficient can be
determined as a characteristic for different contours. The issued water jet is measured using
a measuring device. A Pitot tube detects the total pressure of the flow. The pressure
difference (read on the manometer) is used to determine the velocity.
