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 Total heat transfer area of all the effects is -less than that in a single effect evaporator system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect 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 Total heat transfer area of all the effects is -less than that in a single effect evaporator system Heat transfer co-efficient in a single effect is much lower than that in any effect in a multieffect 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 Harmonic mean temperature difference is given by √(ΔT₁ . ΔT₂) (ΔT₁ - ΔT₂)/(ΔT₁ . ΔT₂) 2.(ΔT₁ . ΔT₂)(ΔT₁ - ΔT₂) 2.(ΔT₁ . ΔT₂)/(ΔT₁ + ΔT₂) √(ΔT₁ . ΔT₂) (ΔT₁ - ΔT₂)/(ΔT₁ . ΔT₂) 2.(ΔT₁ . ΔT₂)(ΔT₁ - ΔT₂) 2.(ΔT₁ . ΔT₂)/(ΔT₁ + ΔT₂) ANSWER DOWNLOAD EXAMIANS APP
