To test the heat transfer for the famous Goodyear blimp, a small-scale prototype is being tested in a wind tunnel. The prototype is a cylinder with 1.2 m diameter and 6 m long. Consider that the wind is blowing across the cylinder (i.e., perpendicular to the cylinder axis) at a velocity of 6 miles-per-hour 1609 m). Ignore the heat transfer rate from the end areas. The wind temperature is 30°C and the surface temperature is uniform at 40°C. Considering this scenario to be dominated by forced convection, what is the convective heat transfer rate from the prototype cylinder? (1 mile =
