Rectangular open channel flow formula
WebbMJK 713 measures and registers flow in open channels and weirs. The formulas are created for ordinary flumes such as Parshall, Venturi and Palmer-Bowlus, but also V-weirs and rectangular weirs can be used. It is also possible to set up a simple formula based on level/flow linearity.
