Mass Transfer The change in enthalpy, when a unit quantity of gas is absorbed by relatively large quantity of adsorbent (on which a definite concentration of the adsorbed gas already exists) is termed as the Heat of wetting Integral heat of adsorption Differential heat of adsorption None of these Heat of wetting Integral heat of adsorption Differential heat of adsorption None of these ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is (1 - f)/f - 1/f - (f - 1)/f - f/(1 - f) (1 - f)/f - 1/f - (f - 1)/f - f/(1 - f) ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Chemical combination or molecular association between unlike molecules takes place in the formation of solution Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Chemical combination or molecular association between unlike molecules takes place in the formation of solution Size of component molecules are not equal ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 1 9 10 8 1 9 10 8 ANSWER DOWNLOAD EXAMIANS APP
