Final answer:

When a surface strainer retains small particles, it causes a large pressure drop due to obstruction. Gravity filtration and suction filtration are methods used to separate solid-liquid mixtures efficiently.


Explanation:

When a surface strainer retains small particles, it causes a large pressure drop to occur. This is due to the reduction in size of the opening and turbulence created by the obstruction, which slows down the fluid passing through.

One example of this phenomenon is in gravity filtration, where fine particles swirl and disperse. Gravity filtration is used when the filtrate will be retained and the solid on the filter paper will be discarded to prevent contamination.

In suction filtration, the force may draw fine crystals through the filter paper pores, leading to loss of material. This method is more suitable for larger crystals and less efficient for microscale work.
