Wind at $20$ km$/$h blows across a $20-$m$-$wide paved highway when the air temperature is $30$C and the pavement is $50$C$.$ Determine the rate of heat transfer from the pavement per unit length due to forced convection. Note that Cp $=1\mathrm{.}007$ kJ$/$kg K$,$ $=0\mathrm{.}0000181$ kg$/$m s$,$ k $=0\mathrm{.}026$ W$/$m K$,$ and $=1\mathrm{.}197$ kg$/$m$3.$
