Determine the local convective heat transfer coefficient (using the correlation for the Nusselt number below) at a position of 0.25 m from the leading edge of a flat plate for each of the following fluids if the flow velocity is 3 m/s and the fluid temperature is 300 K. (a) Air, (b) Refrigerant-134a, (c) Water. For this particular plate, the Nusselt number is: Nu_x = 0.04Re^0.8Pr^0.33.
