A flat plate of width L = 1 m is pushed down with a velocity U = 0.01 m/s towards a
wall resulting in the drainage of the fluid between the plate and the wall as shown in
the figure. Assume two-dimensional incompressible flow and that the plate remains
parallel to the wall. The average velocity, Uavg of the fluid (in m/s) draining out at the
instant shows in the figure is ___________ (correct to three decimal places).
    Correct answer is '(0.05)'. Can you explain this answer?
    Verified Answer
    A flat plate of width L = 1 m is pushed down with a velocity U = 0.01 ...

    Assuming length of plate as B
    Let in infinitely small time ‘dt’ the plate is displaced with ‘dh’
    So,

    As per continuity,
    Rate of mass displaced through plate= Rate of mass displaced between plates and wall


    Since the flow is 2D the velocity of flow in direction perpendicular to plane of paper is
    zero.
