Question

7–2 Cooling of a Hot Block by Forced Air at High

Elevation
The local atmospheric pressure in Denver, Colorado (elevation 1610 m), is
83.4 kPa. Air at this pressure and 20°C flows with a velocity of 8 m/s over a
1.5 m 6 m flat plate whose temperature is 140°C (Fig. 7-13). Determine the
rate of heat transfer from the plate if the air flows parallel to the (a) 6-m-long
side and (b) the 1.5-m side.
