FU stands for Fixture Units, used to represent which in drainage calculations?

Explanation:
Fixture Units are a standardized measure of the hydraulic load a fixture imposes on a drainage system. Each fixture has a fixture-unit value in codes, representing its approximate discharge. This lets you convert diverse fixtures into a common unit and add them to obtain the total load on a branch or main for sizing pipes and fittings. The fixture-unit total roughly corresponds to a flow rate but is not the exact actual flow; it's a design load used in sizing.
