Question

This is a heat transfer course, please explain and show work neatly, and please do not copy from any other solutions because they are incorrect. Thank you so much in advance

Consider atmospheric air at a velocity of V = 20 m/s and a temperature of T= 20C, in cross flow over 10 mm square tube at 45 degrees, maintained at 50C.

1. Sketch
2. Assumptions
3. Calculate the air properties (show the interpolation steps)
4. Re = ?
5. Nu = ? (reference the table number where the equation is obtained)
6. H = ?
7. Calculate the rate of heat transfer per unit length, q.
