Air at 20 °C flows over a flat aluminum plate at 30 m/s to cool electrical components on the other side. The plate measures 80 cm square. The plate is to be kept below a constant temperature of 80 °C, but as it is a conductive metal, we can assume the plate has a constant temperature. Plot h along the plate, Find the average h for the whole plate and, Tell me Q, the total heat dissipated when the plate is at its maximum temperature.
