What is Entrance Loss Coefficient?

The entrance loss coefficient, Ke, is the head loss term of the energy equation for open-channel flow. The head loss coefficient is a measure of the efficiency of the inlet to smoothly transition flow from the upstream channel into the culvert.

What is Normal Depth ?

Normal depth is the depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant. Normal depth occurs when gravitational force of the water is equal to the friction drag along the culvert and there is no acceleration of flow.
