Design issues of oil heat exchangers

New design data for the oil heat exchanger has been received; all the basic parameters are available except for the inlet and outlet temperatures of the fluid. The hydraulic oil flows in the shell side, while water flows in the tube side, with pressures of 1.1/0.5 respectively. Will this have a significant impact on the design? The minimum thickness of the SW6 calculation cylinder is 4.5; the nominal thickness is set at 5. Are there 5 plates of this thickness? Is the plate thickness usually an even number? Choose 5 or 6 (nominal diameter 450). Is there a liquid outlet at the lowest point of the baffle?
Given that your specialty is chemical engineering machinery, it seems that the DATA SHEETS provided for the process in question lack a lot of information. The process requirements should specify the diameter of the heat exchangers, the length of the tubes, the number of tubes, as well as the number of baffle plates, their shape, and the fraction of the tube that is cut away. The pressures are 1.1/0.5 – does this have a significant impact on the design? It shouldn’t. The inlet and outlet diameters for oil and water also need to be specified by the process team. . . . As for the plate thickness, I think 5 and 6 are available.
The parameters are incomplete; without knowing what material it is, and without temperature information, it’s impossible to make a calculation, right?
