Find the heat capacity of the hot and cold fluid.
20,000 lb/hr of air is to be cooled from 150°f to 100°f by water flowing in a shell-and-tube heat exchanger. cooling water is available at 70°f and should leave the exchanger at 95°f. available to do this cooling assignment is a one-shell pass, two-tube pass exchanged consisting of fifty 1-in OD 18 BWG copper tubes, each 10 ft long. the tubes are arranged inside a 10-in shell on a staggered 1-1/4- inch triangular pitch with baffles spaced every 6 in. is this exchanger satisfactory?
A 95kg/hr hot fluid is used to heat a cold fluid from 10oC to 70oC using a double pipe heat exchanger (DPHE). The hot fluid enters at 205°C and leaves the DPHE at 108°C. The Cp of hot fluid is 1.10 kcal/kg°C and the Cp of cold fluid 0.95 kcal/kg°C. a) Calculate the LMTD if the the flow is cocurrent in oC b) Calculate the LMTD if the the flow is countercurrent in oC
