Mass Transfer The change in enthalpy per unit weight of adsorbed gas when adsorbed on gas free or "outgassed" adsorbent to from a definite concentration of adsorbate is called its Integral heat of adsorption Differential heat of adsorption Heat of normal condensation Heat of wetting Integral heat of adsorption Differential heat of adsorption Heat of normal condensation Heat of wetting ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Pick out the correct relationship. (where, Ri = internal reflux ratio Ro = external reflux ratio. ) (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ri) = Ro/Ri (1 - Ri) = Ro/Ri (1 + Ro) = Ro/Ri (1 - Ro) = Ro/Ri (1 + Ri) = Ro/Ri (1 - Ri) = Ro/Ri ANSWER DOWNLOAD EXAMIANS APP
