straight section of asphalt road being built to access a future chemical plant site has a width of 10 m and a length of 4 miles. It receives solar radiation at the rate of 1000 W/m2 . You have applied a special coating to the asphalt that was supposed to reflect almost all radiation, but it turns out there was some false advertising and it only reflects closer to 92.5% of radiation, with the remaining solar radiation being absorbed. All remaining heat transfer between the road and the air occurs through convection due to the wind blowing air at 300 K across the road perpendicular to the lengthwise direction. (Ignore any conduction into the ground.). You can treat the road surface as completely smooth once covered with the coating, but you should note that the Moody plots are only for flow in a pipe, and thus you may need to consult near the end of chapter 12 (depending on your flow over this "flat plate" road). Calculate the minimum wind velocity that is required to maintain the road surface temperature below 325 K and thus prevent melting of the asphalt
