Problem Set 2: Solutions Experimental Setup Figure 1 shows a diagram of the pertinent measurements for the experiment’s equipment. Figure 1: The experimental setup Furthermore, the orifice at the bottom may have one of the three configurations shown in figure 2. Figure 2: Potential orifices at the bottom of the tank For the sample data, the sharp edged orifice was used. Thus, the water can be thought of as exiting at the top edge of the orifice plate, and the plate thickness need not be added to the water height. D = 48.64 cm. 9.06 cm 72.00 cm h Re-entrant nozzle Sharp edged orifice Nozzle
