Two tubes are available for a particular application: (1) 4.0 cm diameter circular tube and (2) 4.0 cm square tube. Air at 1 atm and 27 °C is blown across the tubes with a velocity of 20 m/s. The tube wall temperature is maintained at 50 °C in both cases.

a. Calculate the heat transfer for both geometries if the length of each tube is 1 meter.

b. Which tube should you recommend to your boss and why?
