Question: A horizontal, 2 - in schedule 4 0 pipe is exposed to atmospheric air at 2 0 and has a surface temperature of 9 8

A horizontal, 2-in schedule 40 pipe is exposed to atmospheric air at 20 and has a surface temperature of 98. Determine the natural convection heat transfer coefficient for the outside of this pipe. For a 2-in schedule 40 nominal pipe the inner diameter, ID=2.067 inches and the outer diameter, OD=2.375 inches.
