Q_tri = 1.418*S_w^(5/2)

What is meant by Head?

In hydraulics, Head is a measure of the potential of fluid at the measurement point. or total energy per unit weight above a datum.

What is triangular weir?

Triangular weirs are sharp crested thin plates with V-shaped opening (or notch). These plates are installed at the exit of a channel, tank, or basin in order to measure the real-time flow of water. A typical application for these plates consists in measuring the flow of water on the downstream side of a dam.
