WSFU vs. Flow
How to Use:
- Enter WSFU(Water Supply Fixture Unit). The flow in L/s whill appear in both
cells on the right. One is for systems with mostly flushometer tanks (MFT) and the other
is for mostly flushometer valves(MFV). The calculation is based on the classic Hunter
- For systems with MFV, the minimum WSFU is 5 or more. Therefore, if you need to
calculate the flow for WSFU less than 5, use the MFT results.
- Consult current plumbing code applying to your project for WSFU - Flow relationship.
