A Cole pitometer is set with its orifices at the center of a 40cm pipe. For three different rates ofdischarges, the deflection, “Z” of the carbon tetrachloride (sp.gr. 1.50) in the differential gauge is 65 mm, 185mm and 340 mm.With C = 0.84, what are the discharges? The ratio of the mean velocity to center velocity may be assumed as 0.83.

E2 Name:... Student no:.. Group: ...Date: 5. Questions 5.1 The sum of the clockwise moments and the sum of the anticlockwise moments differ by a small amount. What is this difference in Nm? Why do they differ? 5.2 This not a very accurate experiment. Name one improvement would you suggest for the apparatus to improve accuracy. 5.3. What do you understand by 'equilibrium' for the beam in this practical? 5.4 The meter rule could be fixed in place at the fulcrum and the whole apparatus, with your weights firmly attached, tilted to a constant angle 0 to the horizontal, (bench top). Equilibrium is established again. Would this action change the sum of the clockwise moments and the anticlockwise moments? Explain your answer.
