WebThe behaviour of pipe flow is governed mainly by the effects of viscosityand gravity relative to the inertialforces of the flow. Depending on the effect of viscosity relative to inertia, as represented by the Reynolds number, the flow can be either laminaror turbulent. WebForces in Liquids. The study of liquids is divided into two main parts: liquids at rest (hydrostatics) and liquids in motion (hydraulics). The effects of liquids at rest can often be expressed by simple formulas. The effects of liquids in motion are more difficult to express due to frictional and other factors whose actions cannot be expressed ...
