Gradiente de velocidade em vertedouro triangular
Velocity gradient in triangular weir

Input data

Incoming flow

Water temperature

Square chamber dimension (b)

Chamber depth (D)

Downflow channel depth (y)

Distance between the weir vertex and the bottom of the chamber (yv)

Output data

Flow

Water depth upstream the weir (Hv)

Detention time in the chamber

Velocity gradient

Description

Given the water temperature, the flow to be treated and the desired dimensions of the weir and of the mixing chamber downstream the weir, calculates the water height upstream the weir, the detention time in the chamber and the velocity gradient.
