As your table above is lled with the experimental data from other groups , you are ready to analyze them and nd the answers to the questions posed below and then complete your lab report . By moving from pure water to pure glycerol the viscosity increases by factor of 10 3, while the density changes just by factor of 1.3 see Table l . Therefore , the contribution of the changes in density of glycerol - water mixtures used in these experiments can be neglected .Also , all measurements are done with the same spheres . It should also be noted that the viscosity of glycerol -water mixtures Shows a pronounced sensitivity to temperature .For instance , at room temperatures , the change in q is "' 10% per degree and the change in pm is less than 0.1%. By taking in to account the above ,it can be expected that in the case of purely viscous drag , i.e. according to Stoke's law , the terminal velocity , u (3, must increase linearly with the uidity , lb}, of liquid ,Eq . i127? . The graph on the next page shows the expected dependence of v a on 1111 at 25 0: PI'EdiCth by using $01133 equation , Eq. 31271 This is the dashed line on the graph .5 We can see that both 0 a and lit; should change by factor of 10 3: 50 it's hard to visualize 311 data points varying in such large range of numbers by using a linear scale for both quanties .That's why a base 10 logarithmic scale is used on the graph for both axes .

Please , summarize the obtained experimental results on the last page which should contain the answers to the following questions 112 -3 short sentences per question should be enough Question 1. Was the temperature of water inside the water jacket or inside a 93 cm long tube stable during the experiment ? Why is constant temperature important in this experiment
