Benzene is to be heated in a concentric pipe apparatus having a 1% in ip's inner pipe rom tuu w 140°f by 8000 lb/h of nitrobenzene having an initial temperature of 180°f. a value of u= 100 btu/(h-ft? .°f) may be expected based on the outside surface of the pipe. how much cold benzene can be heated in 160 lin. ft of concentric pipe: a) in countercurrent flow and b) parallel flow? cp values of benzene and nitrobenzene are 0.43 and 0.39, respectively. hint: trial-and-error solution)
