WebThis friction loss calculator uses the Hazen-Williams equation to estimate the pressure or friction loss in pipes. The losses are calculated based on flow rates in circular pipes, the internal diameter of the pipe, the pipe length, and the type of pipe. You can calculate friction loss in five easy steps: WebApr 13, 2024 · Is a separate FDC required for each pressure zone? If you provide just one FDC, and the fire department supplies the system for an upper floor of a high-rise, you will exceed the maximum working pressure of the lower systems.
