A minivan traveling 90 km/h has just passed through a thunderstorm that left a film of water 0.1 mm thick on the top of the van. The top of the van can be assumed to be a flat plate 6 m long. Assume isothermal condi- tions at 27°C, an ambient air relative humidity of 80%, and turbulent flow over the entire surface. What loca- tion on the van top will be the last to dry? What is the water evaporation rate per unit area (kg/s · m2) at the trailing edge of the van top?
