Question: fluids of viscosities 015 nsm2 and 020 nsm2...

Question details

Fluids of viscosities μι = 0.15 Ns/m2 and μ,-0.20 N.s/m2 are contained between two plates (each plate is 1 m2 in area) shown in figure below. The thicknesses are h 0.5 and h2 0.3 mm, respectively. Find the force F to make the upper plate move at a speed of 1 m/s! What is the fluid velocity at the interface between the two fluids?

F V 112 μι
