## Chézy Equation for Laminar Flow in Open Channels

$$ v = C \sqrt{mi} $$ Where \( v \) is the flow velocity, \( C \) is the Chézy coefficient, \( m \) is the hydraulic radius, \( i \) is the hydraulic gradient. $$ m = \frac{A_w}{P_

General Mass Continuity Equation $$ 0 = \frac{\partial}{\partial t} ( \int _{CV} \rho dV ) + \int _{CV} \rho (\overrightarrow{v} \cdot \overrightarrow{n}) dA $$ Where \( \frac{\partial}{\partial t} ( \int _{CV} \rho

Newton's Law of Viscosity $$ \tau = \mu \frac{du}{dy} $$ Where \( \tau \) is stress. \( \frac{du}{dy} \) is the shear rate and \( \mu \) is the viscosity coefficient. Pressure on a 3D
