Air flows past along a sharp edged flat plate with a free stream velocity of $10\frac{m}{s}.$ The plate length and width are $6$ m and $1$ m $.$If the flow is parallel in the direction of length, evaluate the drag on one side of the plate. Take the kinematic viscosity of air as $1\mathrm{.}5{10}^{-5}\frac{m^2}{s}$ and density of air as $1\mathrm{.}2k\frac{g}{m^3}.$ The following relations for local skin friction coefficient, $C_x$ may be useful:

$C_x=0\mathrm{.}664(R{e}_x{)}^{-0\mathrm{.}5}$ for $R{e}_{x}5{10}^5$ and

$C_x=0\mathrm{.}0592(R{e}_x{)}^{-0\mathrm{.}2}$ for $5{10}^5$
