An on the ground hydrogen gas pipeline has an inner
diameter of 0.30m Steel pipe(k=13W/m.K)wall thickness is 0.02m. The
pipe inside forced convection coefficient is 150W/m ̂2.K. The
outside natural convection coefficient from th horizontal pipe
surface to air is20W/m ̂2.K. A) what is the total thermal
resistance B)What is the heat loss from the hydrogenn gas(at290K)
to the cold outdoor still air (270K) per meter of the
pipeline))
