Calculate Chezy Coefficient

The formula for calculating the coefficient of gratitude is: Q=Au. Xie Cai's formula is the main formula for calculating the average flow velocity or head loss along the open channel and pipeline uniform flow.
Uniform flow means that in a constant flow, if the streamlines are straight lines parallel to each other, the flow is called uniform flow. The velocity value is constant, and the flow field with straight and parallel streamlines is the simplest planar flow. For example, the water flow in a straight line pipe with constant diameter, the air flow in a ventilation tunnel with constant cross-sectional shape and size and boundary conditions, all belong to uniform flow.
