Oops, I misread my notes, the formula I used earlier was only for Pr=1 >.< I did as you told me and I got the answer.(at least reasonably close to it) ^^ Thanks a lot!(Sorry if I annoyed you with a lot of stupid mistakes and questions) Here is my working if anyone is interested. Stx =...

Okay thanks for the hint once again. I tried again using Reynold's Analogy. qx/(ρcu∞(T∞-Tw))=τwx/(ρu∞2)hx/c=τwx/(u∞) τwx = (hxu∞)/(c) ∫AτwxdA = 0.86 ∫A(hxu∞)/(c)dA = 0.86 (u∞/c)∫AhxdA = 0.86 (u∞/c)∫AhxdA = 0.86 ∫AhxdA = (0.86c)/u∞ avg h = (1/A)∫AhxdA = (1/A) (0.86c)/u∞ Is this...

Thanks, I'll give it a shot again.

A 2-m x 3-m flat plate is suspended in a room, and is subjected to air flow parallel to its surfaces along its 3-m-long side. The free stream temperature and velocity of the air are 20oC and 7m/s. the total drag force acting on the plate is measured to be 0.86N. Determine the average heat...
