Problem 2. (20 pts) You would like to know the heat transfer
coefficient from a cooling fin operating under
forced convection, but with a length of 1 cm the real fin is just too small to make any measurements. You
make a 10x scale model and test it at the real operating temperatures and 1/10th the ambient airflow
velocity. If your scale model has an h of 5.14 W/m2/K, what is the value of h for the real fin? In both the
real flow and the model testing, the working fluid is air. Assume steady state.
