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 For condensation of pure vapors, if the heat transfer co-efficients in filmwise and drop-wise condensation are respectively hf and hd, then hf could be greater or smaller than hd hf < hd hf = hd hf > hd hf could be greater or smaller than hd hf < hd hf = hd hf > hd ANSWER DOWNLOAD EXAMIANS APP
