Description

Design and rate triangular weirs. This tool allows you to determine the head and flow rate for triangular weirs using Thomson's equation.

 

Q=1.4H5/2Q = 1.4 H^{5/2}

Triangular weir

Available Calculation Methods:

  • Calculate head (H): Determines the water height over the weir based on the flow rate.

    • Inputs: Flow (Q)
    • Outputs: Head (H)

  • Calculate flow (Q): Determines the flow rate for a specific head.

    • Inputs: Head (H)
    • Outputs: Flow (Q)
