Transcribed Image Text:

There are three identical impermeable panels (4 W x 9' Lx 2" T) in the picture below. The Fluid A with a dynamic viscosity of 0.8 cP at 20°C, is placed between top panel and middle panel. During the experiment, while the top panel moves to the left with a velocity of 1 m's, the bottom panel is moving to the right with a velocity of 2 m/s. Which fluid at 20°C should be placed between middle panel and bottom panel to keep the middle panel at rest through out the experiment? Calculate the forces on the plates required to keep them in motion. Please also draw the velocity profile for each fluid between the plates.
