A solution with a boiling point of 180?F boils on the outside of a 1-in. tube with a No. 14 BWG gauge wall. On the inside of the tube flows saturated steam at 60 psia. The convective heat transfer coefficients are 1500 Btu/(h ft2 ?F) on the steam side and 1100 Btu/(h ft2 ?F) on the exterior surface. Calculate the increase in the rate of heat transfer for a copper over a steel tube.GIVENTube with saturated steam on the inside and solution boiling at 180?F outsideTube specification: 1 in.
