Question

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.

Expert Solution
Step 1

Solution :-

Given data :-air at 20 °C

                  flat aluminum plate =30 m/s

                  constant temperature of =80 °C

                  plate measures = 80 cm2 =0.8m
