Question
Two air streams are separated by a thin, perfectly insulating wall. One air stream has a free stream temperature of 15°C and flows with a velocity of 15 m/s, while the other air stream has a free stream temperature of 50°C and flows with a velocity of 5 m/s. Heat is transferred between the air streams via a 4-mm-diameter, 80-mm-long pin fin made of Alloy 195 cast aluminum. Determine the rate of heat transfer between the fluids when the rod is inserted 1 = 30 mm into the cooler air stream. Too 15°C, V = 15 m/s = Air D = 4 mm L = 80 mm 1 Air Too = 50°C, V = 5 m/s
