The total liquid flow rate entering any portion of a fluid-filled (nonleaking) piping assembly will ____ the total flow rate exiting that assembly.

Question

Quizplus · Accepted Answer

This is an application of the law of conservation of mass, which states that mass cannot be created or destroyed, only conserved. In a fluid-filled piping assembly, the mass flow rate (or volumetric flow rate, assuming the fluid is incompressible) entering the assembly must be equal to the mass flow rate exiting the assembly, as mass cannot disappear or materialize out of nowhere. Therefore, the total liquid flow rate entering any portion of such an assembly will always equal the total flow rate exiting that assembly.
