200 m/s over one side of flat plate of length 2.5 m. In the wind tunnel, one measures the friction coefficient to be 10-3 . a) Find the Reynolds number of the flow. b) Using the friction coefficient and Reynolds number find the convection coefficient. State the relation and the assumption clearly. c) Find the minimum heat flux at the plate surface necessary for the surface temperature to remain above zero. Neglect radiation.
