UnitID 100 - WARNING MESSAGES (CALCULATIONS CONTINUE)
The vaporspecific heat of thehot fluid iscalculated in the area of the critical temperature.The
linearinterpolation of the vapor specific heat and the sensible heat duty may beinaccurate in this
region.Specify the vapor specific heat and/or theheat release curve for this case.
Thephysical properties of thehot fluidhave been extrapolated beyond the valid temperature range.
Checkcalculated values.
WARNING-Crossflowvelocity exceeds critical velocity, indicating probability of fluidelasticinstability
andflow-induced vibration damage. If present, fluidelastic instability can leadto large amplitude
vibration andtube damage.
WARNING-Crossflowvelocity at baffle tip exceeds critical velocity, indicating a probability of
fluidelasticinstability and flow-induced vibration damage. If present, fluidelasticinstability can lead
to largeamplitude vibration and tube damage.
NOTE-Tubevibration from vortex shedding is possible. Check the crossflow-inducedvibration
amplitude onLine 27 of the Vibration Analysis report for an asterisk. If no asteriskprints, probability
of tube damageis low.
NOTE-Tubevibration from turbulent buffeting is possible.
Bundleentrance velocity exceeds 80% of critical velocity, indicating thatfluidelastic instability and
flow-inducedvibration damage are possible. Fluidelastic instability can lead to largeamplitude
vibration andtube damage.
WARNING-Shellentrance velocity exceeds critical velocity, indicating a probability offluidelastic
instabilityand flow-induced vibration damage. If present, fluidelastic instability canlead to large
amplitudevibration and tube damage.
Bundle exitvelocity exceeds 80% of critical velocity, indicating that fluidelasticinstability and
flow-inducedvibration damage are possible. Fluidelastic instability can lead to largeamplitude
vibration andtube damage.
WARNING-Shellexit velocity exceeds critical velocity, indicating a probability offluidelastic instability
andflow-induced vibration damage. If present, fluidelastic instability can leadto large amplitude
vibration andtube damage.
WARNING-Shellentrance rho-v-squared exceeds TEMA maximum recommended value of5950
kg/m s2 (4000lb/ft sec2).
WARNING-Shellexit rho-v-squared exceeds TEMA maximum recommended value of 5950 kg/m s2
(4000 lb/ftsec2).
Xvib can beused for a more detailed analysis of individual tubes in the bundle.
The inletunsupported span length (inlet baffle spacing + central baffle spacing)exceeds the TEMA
maximumunsupported span length.
The centralunsupported span length (twice the central baffle spacing) exceeds the TEMAmaximum
