1. The sliding plate viscometer shown is used to measure the viscosity of a fluid. The top plate is moving to the right with a constant velocity of 10 m/s in response to a force of 3 N. The bottom plate is stationary. What is the viscosity of the fluid? Assume a linear velocity 100 mm 50 mm I mm distribution. 2. Sometimes the sidewalks at WSU get icy leading to risky falls by pedestrians. Some options to reduce this risk is to coat the ice with a thin film of a fluid that doesn't freeze at such temperatures, such as ethyl alcohol or SAE 10W-30 motor oil. Which would prevent falls more? Assume the densities of both fluids are the same, and use Figure A.3 with temperature of 0C. D-
