3. If the local atmospheric pressure in $$\mathrm{Al}$$ Madinah $$\mathrm{Al}$$ Munawarah, $$\mathrm{KSA}$$, is $$100\mathrm{kPa}$$. Air at this pressure and at $$30^{?}\mathrm{C}$$ flows with a velocity of $$6\mathrm{m}/\mathrm{s}$$ over a $$3?\mathrm{m}\times 6?\mathrm{m}$$ flat plate whose temperature is $$120^{?}\mathrm{C}$$. Determine the rate of heat transfer from the plate if the air flows parallel to the: (6 points) a) 6-m-long side b) 3-m side.
