A water-to-water system is used to test the effects of changingtube length, baffle spacing, tube pitch, pitch layout, and tubediameter. Cold water at 25°C and 100,000 kg/hr is heated by hotwater at 100°C , also at 100,000 kg/hr. The exchanger has a 31 in.ID shell. Perform calculations on this 1–2 shell-and-tube heatexchanger for the following conditions, as outlined in theexamples, and put together an overall comparison chart. a. 3/4 in.OD tubes, 12 BWG laid out on a 1 in. triangular pitch; 3 bafflesper meter of tube length. Analyze the exchanger for tube lengths of2, 3, 4, and 5 m. b. 3/4 in. OD tubes, 12 BWG laid out on a 1 in.triangular pitch; 2 m long. Analyze for baffle placement of 1baffle per meter of tube length, 2 baffles per meter of tubelength, 3 baffles per meter of tube length, 4 baffles per meter oftube length, and 5 baffles per meter of tube length. c. 3/4 in. ODtubes, 12 BWG; 2 m long; 4 baffles per meter of tube length.Analyze the exchanger for tube layouts of 15/16 in. triangularpitch, 1 in. triangular pitch, and 1 in. square pitch. d. 1 m ODtubes, 12 BWG; 4 m long; 9 baffles. Analyze the exchanger for tubelayouts of 1.25 in. triangular pitch and 1.25 in. square pitch. e.3/4 in. OD tubes, 12 BWG laid out on a 1 in. triangular pitch; 2 mlong; 4 baffles per meter of tube length. Analyze the exchanger for2, 4, 6, and 8 tube passes, and compare to the case of truecounterflow (i.e., 1 tube pass).
