Fluid Mechanics Lab: Discharge Coefficient for Notches Experiment

This lab report details an experiment conducted to determine the discharge and discharge coefficient over rectangular and triangular (Vee) notches. The experiment involved setting up a hydraulic bench with a weir channel, rectangular and Vee notch weirs, and a graduated measuring tank. The procedures included placing the weir plate, starting the pump, measuring water levels and flow rates at various crest heights, and repeating the process for both notch types. The report includes the theoretical background, relevant formulas for calculating discharge coefficients, and tables of readings for both notch types. Observations, calculations, and graphs were presented to analyze the relationship between the height of water and the flow rate. The report also discusses assumptions made during the experiment and provides recommendations for improving accuracy. References to relevant fluid mechanics texts are also included. The goal is to apply what is learned in class practically, and to expand skills of data collection, analysis as well as data presentation which is achieved through report writing. The practical part shall constitute 30% of the total grade to be awarded to each student.
