number of fixture units
a parameter in sizing a drainage pipe
The number of fixture units (FU) is a measurement used in plumbing design and engineering to determine the required size of pipes and the flow rate of water in a plumbing system. A fixture unit represents the amount of water that flows through a plumbing fixture or appliance during a specific period.
Each fixture is assigned a fixture unit value based on the fixture’s size, type of appliance, and anticipated water usage. For instance, a standard lavatory sink is typically assigned a value of 1.0 fixture unit, while a bathtub is assigned a value of 2.0 fixture units. Water closets or toilets may have a value ranging from 3 to 6 fixture units, depending on the model and type.
The total number of fixture units in a plumbing system is calculated by adding the fixture unit value of each plumbing fixture or appliance that is connected to the system. This information is then used to determine the required pipe size, flow pressure, and other specifications necessary for the plumbing system to function correctly and efficiently.
In summary, the number of fixture units is a critical factor in designing an efficient and effective plumbing system. It helps to ensure that the plumbing system can handle the anticipated water usage without experiencing issues such as low water pressure, clogs or backups, or other plumbing problems. Accurate calculations of the fixture units are necessary in providing safe and reliable plumbing systems for commercial, industrial, or residential buildings.
