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...
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...
