The purpose of a bypass line around a system filter is to:

A bypass line around a system filter is designed primarily to allow fluid to flow around the filter when conditions require it. This could occur during maintenance, filter replacement, or in emergency situations where the filter is clogged or inoperative. By providing an alternative path for flow, the bypass line ensures that the system continues to function and maintain flow even if the filter is compromised.

While options regarding pressure regulation, resistance to flow, and space considerations are relevant to system design, they do not specifically capture the primary function of a bypass line. The bypass is essential for maintaining system continuity and protecting equipment during unforeseen circumstances, highlighting its critical role in ensuring ongoing operational efficiency.
