Transcribed Image Text:4.38 Two liquids with different densities and viscosities fill the
gap between parallel plates as shown in Fig. P4.38. The bottom
plate is fixed; the top plate moves with a speed of 2 ft/s. The ve-
locity profile consists of two linear segments as indicated. The
fixed control volume ABCD coincides with the system at time
1 = 0. Make a sketch to indicate (a) the system at time t = 0.1 s
and (b) the fluid that has entered and exited the control volume
in that time period.
