(20pts) Installing Fins to Increase the Efficiency of a Process using Steam to Heat Water Steam is being used to heat water and it has been suggested that aluminum fins should be added to one side of the mild steel wall separating the two fluids to increase the heat transfer process. The process and equipment specifications are given below. a) To which side of the mild steel wall should aluminum fins be added to provide the greatest fin efficiency (i.e., best return on capital investment)? Show calculations to support your choice. b) Would this result in the greatest increase in heat transfer rate? Discuss your answer based on your answer in part a) and known parameters with reference to the Fin Design Equation (Welty Eq. 17.48). Wall: 1mx1m mild steel Fins: Aluminum with L=2.54cm and thickness (2t)=3.0mm Aluminum: k=230W/mK, Steam Side: T=500K,h( steam )=5000W/m2K Water Side: T=293K,h (water) =500W/m2K
