Warnings and MessagesDescription

1062 A default allocation of Hot stream 1: to the tubeside has been made. It is estimated that the chances of this being correct are about 55 percent. Potentially important factors, such as a fluid being hazardous, or having material compatibility problems, could not be allowed for. Such fluids would usually go on the tubeside.

1063 No Maximum Allowable Pressure Drop was specified for either stream. Estimated values of 0,26 bar (hot side) and 0,26 bar (cold side) were used. Design results are usually very susceptible to at least one of these values, and the estimates may not match your process requirements. Treat the exchanger designs produced with caution.

1860 The consolidated process conditions for Stream 1, prior to the main calculations, give a heat load of -150 kW, for a flow of 1,791 kg/s, with outlet temperature 70 C and quality (vapor mass fraction) 0.

1860 The consolidated process conditions for Stream 2, prior to the main calculations, give a heat load of 150 kW, for a flow of 3,7315 kg/s, with outlet temperature 60 C and quality (vapor mass fraction) 1.

1258 A nominal baffle cut of 40 percent has given local cuts of 38,04348 and 38,04348 percent, to match the tube line locations. The effective (mean) cut used in the calculations is 38,04348 percent. [for double segmental baffles, this refers to the outer cuts]

1446 The Advanced calculation has converged after 26 iterations

1701 Design calculation successfully completed.

1611 The HTFS flow induced vibration analysis has identified possible or serious problems in one or more areas: Fluid Elastic Instability: 6 warnings, of which 5 serious; Resonance Assessments: 16 warnings, of which 0 serious.

1615 The HTFS and/or TEMA flow induced vibration analysis has identified the possibility of acoustic resonance. You should consider using a deresonating plate, especially if there is resonance of the vortex shedding or turbulent buffeting frequencies with both the acoustic and natural frequencies

1643 The tube side is high fouling and the front head is a bonnet. You may wish to change to a removable channel cover (A, C or N) for ease of mechanical cleaning.

1902 The number of baffles 2 in a shellside flow path is small. Some of the assumptions in the Shell&Tube thermal model and temperature difference calculation are less valid than normal.
