A thin plate moves between two parallel, horizontal, stationary flat surfaces at a constant A thin plate moves between two parallel,

horizontal, stationary flat surfaces at a constant

$($velocity of $5\frac{m}{s}.$ The two stationary surfaces are

spaced $4$ cm apart. and the medium between them

is filled with oil whose viscosity is $10$ Poise. The

part of the plate immersed in oil at any given time

is $2-m$ long and $0\mathrm{.}5-m$ wide.

Determine

The drag force required to maintain this motion when

The thin plate moves through the mid$-$plane between the two

stationary surfaces.

The thin plate was $1$ cm from the top surface $(h_1)$ and $3$ cm from the

bottom surface $h_2.$

The power utilized in overcoming viscous resistance in both cases.
