The viscosity ? of a liquid can be calculated using equation: ? = B?t, where B is calibrationconstant of the viscometer, ? is the density of the liquid and t is time of flow through theviscometer. In one experiment, water was used to calibrate the viscometer at 25.0?C, and thetime of flow was measured as 200.3?0.2 s. At 25.0?C, the density and viscosity of water are0.99708 g?mL−1and 8.909 ? 10−3g?cm−1?s−1, respectively. Using the same viscometer, thetime of flow was 425.6?0.5 s at 25.0?C for an unknown liquid with density 0.85667 g?mL−1.Determine constant B and the viscosity of the unknown liquid with error analysis.
