How are the average temperature along the length of the cylinder and the average temperature along the length of the heat exchange tubes calculated in the SW6 fixed-type heat exchanger?

Please have a professional respond – when using SW6 to calculate fixed-plate heat exchangers, how exactly should this be done? Our process team requires us to carry out the calculations ourselves
If the design unit has the process, it should be provided by the process team. If it is designed by the manufacturing unit and these two parameters are not listed in the data sheet, generally the average of the inlet and outlet temperatures is used for the shell side (as specified in P120 of GB/T151), while the average of the four temperatures on both the tube side and the shell side is used for the tube side (it’s not entirely accurate, but it can serve as a reference).
