QUESTION 1. An orifice meter (Dorifice = 15.9mm and D pipe = 26mm) is calibrated in the laboratory with water as the working fluid and with an air-over-water, inverted U-tube manometer. Given data is discharge coefficient of 0.616 & h of 38.1 +/- 10% mm of H2O. Assume no uncertainties associated with the diameters. Estimate the actual flow rate in L/s from the orifice for given operating point.
QUESTION 2. A venturi meter (Dpipe = 26.65 mm & Dthroat = 15.8 mm ) is calibrated in the laboratory using water as the working fluid and an air-over-water, inverted U-tube manometer. Data obtained are as follows: Q ac of 2.21 x 10 -4 +/- 10% m 3 /s & discharge coefficient of 0.99. What is the h in mm of H 2 O? Assume no uncertainties associated with the diameters.
