The WSFU (Water Supply Fixture Units) is defined by the Uniform Plumbing Code (UPC) and can be used to determine water supply to fixtures and their service systems. Note that this conversion is only true for one or a few fixtures.

The Water Supply Fixture Unit - WFSU - is defined by the American Uniform Plumbing Code (UPC) and is used to calculate the demand in water supply systems. One WFSU for a singel unit corresponds to one GPM, or. The conversion can only be used for one or a few fixtures.

2022年12月5日 · The WSFU is a sizing tool that helps estimate peak water demand for intermittent-use fixtures. It is an assigned value, not a measurement, that factors in how often the fixture is likely to be used, as well as the amount of water required to function, and how that water is used by the fixture.

Explore our Water Pipe Sizing Charts. Understand WSFU, fixture branch pipe sizes, and flow rate considerations for optimal water supply.

Appendix E provides several methods that could be used by a system designer. E101.1 Scope. This appendix outlines two procedures for sizing a water piping system (see Sections E103.3 and E201.1).

For fixtures not listed, choose a w.s.f.u. value of a fixture with similar flow characteristics. For SI: 1 gallon per minute = 3.785 L/m. The fixture-unit value 2.5 assumes a flow demand of 2.5 gallons per minute, such as for an individual lawn sprinkler device.

Water Supply Fixture Units (WSFU) is the standard method for estimating the water demand for a building. This system assigns an arbitrary value called a WSFU to each fixture in a building, based on the amount of water required and the frequency of use.

2023年5月25日 · Water supply fixture unit (WSFU) is a measure of the flow rate of water through a specific fixture. The WSFU of a fixture can be found in the plumbing code or by consulting a plumbing engineer. Here we show several different codes and the various tables they use for fixture unit values.

The water supply fixture unit (WSFU) is a factor so chosen that the load-producing effects of different kinds of fixtures under their conditions of service can be expressed approximately as multiples of that factor. WSFUs for two or more fixtures can then be added to determine their combined effect on the water piping system.

Table B.5.3 lists water supply fixture unit values for typical groups of fixtures in bathrooms, kitchens, and laundries in dwelling units. There is more diversity in the use of the fixtures in these groups than is reflected by WSFU values for the individual fixtures.
