Francisco did his final year research project batch experiment on Zn (II) adsorption on kaolin
at a solution pH of 5.8. The reaction volume was 0.025 L and mass of adsorbent was 0.1
gram.

Prob 2
A single-effect, vertical short-tube evaporator is used to concentrate a food-based
syrup from 10% to 40% at the rate of 2000 kg of feed per hour. The feed enters at
