Question: Let air at a constant velocity of 7.6 mis, a temperature of 90°C, and 1 atm pressure flow along a smooth, flat surface. Let the plate be divided into three sections, each 10em in flow length. The first 10ern section is maintained at 40°C, the second at BO°C, and the third at 40°C. Evaluate and plot the heat flux at all points along the 30 cm of plate length, and find the local heat-transfer coefficient.
