This isFor a steadily flowing incompressible fluid, the continuity equation A·v = constant means:Bernoulli's equation for steady, non-viscous, incompressible flow along a streamline reads:A horizontal pipe narrows from A₁ to A₂ < A₁. Compared to the wider section, in the narrower section the fluidThe terminal velocity v_t of a small sphere of radius r falling in a fluid of viscosity η is given by Stokes' Reynolds number Re is dimensionless and given by Re = ρ v d / η, where d is a characteristic length. For Re ≪ Surface tension T of a liquid is best defined as:The excess pressure inside a spherical liquid drop of radius R and surface tension T is:The height to which a liquid rises in a capillary tube of radius r is (with surface tension T, contact angle θA liquid emerges from a hole at depth h below the free surface of a large open tank. The exit speed (TorricellTwo soap bubbles of radii R₁ < R₂ are connected by a tube. Air flows:A solid object floats with 80 % of its volume submerged in water (ρ_water = 1000 kg m⁻³). The density of the oPoiseuille's law gives the volume flow rate Q of a viscous fluid through a horizontal pipe of length L and rad
