Saturated steam at 40 psia flows at 5 fps through a schedule-40,
-in. steel pipe. The convective heat-transfer coefficient by condensing steam on the inside surface may be taken as 1500 Btu/h ft²
F: The surrounding air is at 80F, and the outside surface coefficient is 3 Btu/ft²
F: Determine the following:

a. The heat loss per 10 ft of bare pipe.

b. The heat loss per 10 ft of pipe insulated with 2 in. of 85% magnesia.

c. The mass of steam condensed in 10 ft of bare pipe.
