During the washing of cake_________________?
Correct answer: A. All the resistances are constant
- A. All the resistances are constant
- B. Filter medium resistance increases
- C. Filter medium resistance decreases
- D. Cake resistance decreases
Explanation
In ordinary cake washing, the cake and filter-medium structure is assumed unchanged, so their hydraulic resistances remain constant. A decrease in cake resistance would require removal or breakdown of the cake structure, which is not the normal assumption.
