Applied Hydraulics #$1\mathrm{.}4\mathrm{.}5$

A very thin plate measuring $6$ in$.$ by $18in.$ is being pulled between two stationary plates $($Figure P$1\mathrm{.}4\mathrm{.}5)$ at a speed of $1\mathrm{.}5$ ft$/$s $?$ The $0\mathrm{.}5$ inch space between the two plates is filled with lubricating oil with a dynamic viscosity of $0\mathrm{.}0065$ lb$-$s$/$ft$^2.$ How much force $(F)$ is required to pull the thin plate?
