A viscous fluid flows past a flat plate such that the boundary layer thickness at a distance $1\mathrm{.}2$ m from the leading edge is $10$ mm $.$ If the upstream velocity of the flow is $U=1\mathrm{.}4\frac{m}{s}$ determine the kinematic viscosity of the fluid. Assume laminar flow.

$v=\frac{m^2}{s}$
