The sliding plate viscometer is used to measure fluid viscosity. The top plate (100 mm x 50 mm) is moving to the right with a constant velocity of 22 m/s in response to a force of 1 N. The bottom plate is stationary and separated by a vertical distance of 1 mm from the upper plate. What is the viscosity of the fluid? W F ng L moving plate stationary plate fluid

B1. Determine the kinematic viscosity of the fluid between the plates as shown in Figure B1 given the following information: F = 5N h = 0.5mm v = 7m/s L=21 cm w = 10cm SG= 0.80 Moving plate Stationary plate Fluid Figure B1 V

Problem 3: A honeybee farmer wants to measure the absolute viscosity of his honey. You suggest dropping a 4mm steel ball into a container of honey and measure the time it takes for the ball to pass between two marks as shown. If the time is 13 seconds, what is the honey's viscosity. Assume the density of the honey is 1450 kg/m3 and the density of the steel ball is 7800 kg/m³. Honey 5 cm

A plate separated by 0.1 mm from a fixed plate moves at 0.10 m/s under a force per unit area of 2.0 N/m2. Determine the viscosity of the fluid between the plates. Give your answer in units of mPaos and round to the nearest whole number.
