A manufacturing plant produces an efluent as a waste product. As part of a waste heat recovery system, they want to use this for internal heating and cooling. The effluent is flown through a system where its temperature remains at 303.15 K. A 0.06-m diameter pipe carrying hot water and 0.04-m diameter pipe carrying cold air is passed through this effluent chamber. It can be assumed that the surface temperature of these air and water pipes are same as the effluent temperature. Water comes in at 328.15 K and exits at 308.15 K. The air comes in at 268.15 K and exits at 298.15 K. The mass flow rate of water and air is respectively, 1 kg/s and 0.01 kg/s. Determine the length of the water and air pipes in the system. Convert all calculations to C.
