WebThe velocity gradient is proportional to the shear force per unit. x is the distance perpendicular to the surface. In order to make relationship 5.1 into an equation a constant of proportionality is required, i.e. when η is termed the coefficient of viscosity (or more usually “the viscosity” of the fluid). WebStream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). ... This increases the gradient which causes the water to flow faster which increases erosion and transport, which then reduces the gradient. In the lower reaches of a stream, where the discharge is greater, since ...
