Plot the results to obtain a slope, use y-mX+C to obtain y, and m which will be your discharge coefficient Cd. la Volume Time taken π(Dc)² Q₁ [1–²*120(ha [2g (ha-hc)] Use Dc-0.016 and DA=0.026. E F

Flow Rate Measurement with Venturi Meter Use the four calculated Qa and Qi values in the previous section, compare to the Q. (venturi) values )calculate using the methods below), and calculate the differences in percentage. Show your results in a table form showing all values of Q₁, Q₁, Qa (venturi) and the error rates. Qa(venturi) = CaQi Use the discharge coefficient Ca value from the previous section. % error Qa(venturi) - Qa (volumetric) Qa(venturi) x 100% (0.000315 m³/s) - (0.000315 m³/s)| % error = x 100% 0.000315 m³/s % error = 0% Bernoulli's Theorem Demonstration Collection time of the water in the volumetric tank: 1 minute Four different Qav flow rates are applied, shown in the tables. Use diameter values obtained from the attached image of the Venturi tube for the respective tapping points. For example, use D=0.026 for cross-section A, D-0.0216 for cross-section B, so on so forth. Refer to the following tables, head values are collected for the different sections of the tube. Calculate the remaining values, and notice the differences. Write down your observations discussing if they are affected by factors, eg. Energy loss, velocity versus flow-rate, et cetera. Your discussion should be limited to maximum one A4 page.
