2. Heat dissipated from an engine in operation can cause hot spots on its surface that can cause leaked oil to ignite spontaneously. To avoid that, the engine cover surface should be kept below 180C. Consider a 2-m long engine cover that is dissipating heat at the rate of 1200 W/m. It is cooled by air flowing parallel to it at a velocity of 7.7 m/s and a temperature of 60C. Determine whether the cooling will be enough to maintain the surface temperature no higher than 180C. The properties of air at 120C are Pr = 0.707, k = 0.0324 W/m-C, and v = 2.522 x 10-5 m/s
