Font Paragraph Drawing ANALYSIS V a) Plot on the same set of axes the values of flow rate against pressure gradient for each of the three Ap 1 tubes. Ap Make sure that your largest and your largest values can be plotted on your graph. To make it easier to plot the points, it is a good idea to use the same power of 10 for all the values, and the same power of 10 for all the values, when entering values into the tables. 1 Each set of points should fall on a straight line passing through the origin. Explain why this is so. In practice the points for larger pressure gradients lie on curves with lower flow rates. This is because at large pressure gradients the water is accelerated at the entrance to the tube, and less energy is available to do work against the viscous forces. Draw straight lines passing through the origin and the lowest flow rate point for each tube. Explain why the line for the largest tube has the largest slope. b) Calculate the slope of the line for tube no. 3 (r-0,9 mm), and from it calculate the viscosity of water. Slope of line= Viscosity of water n= Nates Comments 6:17 PM 15°C 21 17 CO PR ENG Editing
