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