Hi,
I am Rating/Checking my manual (made by paper following Kern's book algorithm) to design (preliminarly) a Shell and Tubes HeatExchanger. After all the inputs and running the Rating programm in Aspen EDR I get this warning message,
"There is a full support baffle (blanking baffle) present (specified or default for S and T type rear heads), but the distance beyond this baffle has not been specified. The distance beyond the blanking baffle has been calculated as 12,312 in. For U-bends, this distance is the estimated support plate thickness 0,5 in. For S-type rear heads, the distance is two tubeplate thicknesses (4,1875 in) plus the greater of 100mm or the estimated support plate thickness. For all other rear head types, the calculated distance beyond the blanking baffle is the tubeplate thickness plus the greater of 100mm or the estimated support plate thickness."
What does it means? I do not have the information of the "distance beyond this baffle" that the message indicate.
