Webwhere I f is the flow index; ω 1, N 1 are the water content and the number of blows at any point 1 on the flow curve, respectively; and ω 2, N 2 are the water content and number of blows at any point 2 on the flow curve, respectively. Flow index indicates the rate at which a soil mass loses its shear strength with the increase in water ...

WebBernoulli’s equation in fluid mechanics states that, for steady flow of non-viscous incompressible flow, the total head at a point can be expressed as the summation of three independent components, namely, pressure head, elevation head and velocity head. This is shown in Eq. 7.1. (7.1) g 2 p Total head Pressure head Elevation head Velocity ...
