Asimple viscometer can be constructed as in the drawing. a mass of 10 g pulls a block of mass 1 kg on a thin layer of oil of thickness 0.1 mm. the dimensions of the block are height 10 cm, length in the plane of the picture 20 cm and width into the picture 10 cm. m l h oil thickness = h m a. if the block moves to the left with a velocity of 10 cm/sec, what is the viscosity of the oil in cp? b. if the mass on the pulley were increased to 100kg, would this method of measuring viscosity still be appropriate? why or why not? the actual measurements of the velocity (in cm/sec) were 10, 10.1, 9.8, 9.9 and 10.1. c. what is the best estimate of the viscosity in cp? d. what is the uncertainty in the estimate of the viscosity in cp?
