A one-shell pass, two-tube pass heat exchanger (1-2) is to cool at mh= 1.5 kg/s
oil (Cph = 2100 J/kg. oC) from Th,in = 90 oC to Th,out = 40 oC with water (Cpc = 4180
J/kg.oC) entering at Tc,in = 19 oC and mc = 1 kg/s. The overall heat transfer
coefficient Um is 250 W/m2.oC. Design the heat exchanger requires for the
process by using 2.5 cm (OD), 2.2 cm (ID) and 5.5 m long tubes. How will the design values change if the two-shell pass, four-tube pass exchanger (2-4) is
designed? Discuss your results.
