Question:
Fluids of viscosities \(\mu_{1}=0.1 \mathrm{~N} \cdot \mathrm{s} / \mathrm{m}^{2}\) and \(\mu_{2}=0.15 \mathrm{~N} \cdot \mathrm{s} / \mathrm{m}^{2}\) are contained between two plates (each plate is \(1 \mathrm{~m}^{2}\) in area). The thicknesses are \(h_{1}=0.5 \mathrm{~mm}\) and \(h_{2}=0.3 \mathrm{~mm}\), respectively. Find the force \(F\) to make the upper plate move at a speed of \(1 \mathrm{~m} / \mathrm{s}\). What is the fluid velocity at the interface between the two fluids?
