(Problem 8) Assume that the external surface temperature of a horizontal pipe is maintained at 323K (steady state). The pipe is in a medium whose atmospheric air temperature is 298K. The pipe is 0.3 meters in diameter and 10 meters long. What is the convective heat rate between the pipe and the air for the case when the ambient air is still and for the case when the ambient air approaches transversely with a velocity of 10km/h
