Heat Transfer Arithmetic mean area can be used in heat transfer problem to calculate the heat flow by conduction through a cylinder which is Having the value of Ao/Ai > 2 Thin walled having the value of Ao Ai/< 2 Thick walled Both B and C Having the value of Ao/Ai > 2 Thin walled having the value of Ao Ai/< 2 Thick walled Both B and C ANSWER DOWNLOAD EXAMIANS APP
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 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 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 ANSWER DOWNLOAD EXAMIANS APP
