How do you convert water supply fixture units to GPM?
WebWhere discharges to a waste receptor or to a drainage system are only known in gallons per minute (liters per second) values, the drainage fixture unit values for those flows shall be computed on the basis that 1 gpm (0.06 L/s) of flow is equivalent to two drainage fixture units. Upcodes Diagrams Related Code Sections WebThe relationship between gallons per minute (gpm) and fixture unit is not constant, but varies with the number of fixture units. For example, 1000 FU is equivalent to 220 US gallons per minute (0.014 m 3 /s) while 2000 FU represents only 330 US gallons per minute (0.021 m 3 /s), about 1.5 times the flow rate. linsay tablet case
