Heat Transfer A dilute aqueous solution is to be concentrated in an evaporator system. High pressure steam is available. Multiple effect evaporator system is employed, because Boiling point elevation in a single effect system is much higher than that in any effect in a multieffect system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect system Total heat transfer area of all the effects is -less than that in a single effect evaporator system Total amount of vapor produced per Kg of feed steam in a multiple effect system is much higher than in a single effect Boiling point elevation in a single effect system is much higher than that in any effect in a multieffect system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect system Total heat transfer area of all the effects is -less than that in a single effect evaporator system Total amount of vapor produced per Kg of feed steam in a multiple effect system is much higher than in a single effect ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Vibrations in the tubes of a shell and tube heat exchanger is induced due to the All of these Vibrations transmitted through piping and/or supports due to external reasons Oscillations in the flow of shell/tube sides fluid Flow of fluid on the tube and shell sides All of these Vibrations transmitted through piping and/or supports due to external reasons Oscillations in the flow of shell/tube sides fluid Flow of fluid on the tube and shell sides ANSWER DOWNLOAD EXAMIANS APP
