Problem #2: A thin plate of Vp = 40x40x0.1 cm3 size is falling vertically in a narrow slit as shown in Fig 2. The plate thickness is assumed to be negligible as compared to the slit width of a = 1.5 cm. The slit is filled with a 100-cp oil. Determine the density of plate material required to set the plate in motion at a constant velocity ofu= 0.2 m/s. Oil density is pf= 0.8 g/ml. wwww %3D %3D Slit a = 1.5 cm b=1 cm Figure 2 Problem #2: A thin plate of Vp = 40x40x0.1 cm3 size is falling vertically in a narrow slit as shown in Fig 2.
