For horizontal discharge from a tank, the shape of the outlet and the outlet velocity affect the trajectory of the water jet. In hydrodynamics the interaction between the trajectory, the shape of the outlet and the outlet velocity during discharge from tanks are described and are essential, for example, in hydraulic engineering for the design of dams.
HM 250.06 includes a transparent tank with a horizontal outlet in which various inserts can be installed. The resulting trajectory of the water jet is digitally recorded in the following transparent experimental section. A depth slide gauge is used to measure the trajectory of the water jet in 8 predefined positions.
The measured values are transferred to the HM 250 base module and displayed as a curve on the touch screen. The level in the tank is set and automatically controlled via the base module.
Four outlet inserts with different diameters and inlet contours are provided along with the unit. The pressure loss coefficient can be determined as a characteristic for different inserts. Thus, the influence of the level in the tank and the pressure loss coefficient on the trajectory can be investigated.
The accessory HM 250.06 is easily and securely positioned on the worktop of the HM 250 base module. Via RFID technology the accessories are automatically identified, the appropriate GUNT software is loaded and an automatic system configuration is performed. The intuitive user interface guides through the experiments and displays the measured values graphically. For tracking and evaluation of the experiments, up to 10 external workstations can be used simultaneously using the local network via LAN connection. HM 250 supplies the water and is used to measure the flow rate and the pressure.
