Rating - Horizontal Multipass  Flow TEMA BEM Shell With Single-Segmental Baffles
Unit  ID 100 - WARNING MESSAGES (CALCULATIONS CONTINUE)
The vapor  specific heat of the  hot fluid is  calculated in the area of the critical temperature.  The
linear  interpolation of the vapor specific heat and the sensible heat duty may be  inaccurate in this
region.  Specify the vapor specific heat and/or the  heat release curve for this case.
The  physical properties of the  hot fluid  have been extrapolated beyond the valid temperature range.
Check  calculated values.
WARNING-Crossflow  velocity exceeds critical velocity, indicating probability of fluidelastic  instability
and  flow-induced vibration damage. If present, fluidelastic instability can lead  to large amplitude
vibration and  tube damage.
WARNING-Crossflow  velocity at baffle tip exceeds critical velocity, indicating a probability of
fluidelastic  instability and flow-induced vibration damage. If present, fluidelastic  instability can lead
to large  amplitude vibration and tube damage.
NOTE-Tube  vibration from vortex shedding is possible. Check the crossflow-induced  vibration
amplitude on  Line 27 of the Vibration Analysis report for an asterisk. If no asterisk  prints, probability
of tube damage  is low.
NOTE-Tube  vibration from turbulent buffeting is possible.
Bundle  entrance velocity exceeds 80% of critical velocity, indicating that  fluidelastic instability and
flow-induced  vibration damage are possible. Fluidelastic instability can lead to large  amplitude
vibration and  tube damage.
WARNING-Shell  entrance velocity exceeds critical velocity, indicating a probability of  fluidelastic
instability  and flow-induced vibration damage. If present, fluidelastic instability can  lead to large
amplitude  vibration and tube damage.
Bundle exit  velocity exceeds 80% of critical velocity, indicating that fluidelastic  instability and
flow-induced  vibration damage are possible. Fluidelastic instability can lead to large  amplitude
vibration and  tube damage.
WARNING-Shell  exit velocity exceeds critical velocity, indicating a probability of  fluidelastic instability
and  flow-induced vibration damage. If present, fluidelastic instability can lead  to large amplitude
vibration and  tube damage.
WARNING-Shell  entrance rho-v-squared exceeds TEMA maximum recommended value of  5950
kg/m s2 (4000  lb/ft sec2).
WARNING-Shell  exit rho-v-squared exceeds TEMA maximum recommended value of 5950 kg/m s2
(4000 lb/ft  sec2).
Xvib can be  used for a more detailed analysis of individual tubes in the bundle.
The inlet  unsupported span length (inlet baffle spacing + central baffle spacing)  exceeds the TEMA
maximum  unsupported span length.
The central  unsupported span length (twice the central baffle spacing) exceeds the TEMA  maximum
