Copper pipes, carrying hot water at 180F, are imbedded in the floor-ceiling as illustrated in Fig. III.1 in order to heat the rooms above and below. The outer diameter of the pipes is 1 in. and the resistance to heat transfer in the water and the pipe wall is negligible. If the top surface is at 60F and the bottom surface is at 83F, what are the average heat fluxes upwards and downwards from the hot water pipes? Take the thermal conductivity of the floor-ceiling material to be 0.42 Btu/hrft F. 6 in T = 60F 4 in Fig. III.1 Use of hot water for heating apartments.
