Webb18 okt. 2016 · Fish surfaces are remarkably diverse and in many bony fishes scales can have an intricate surface texture with projections, ridges, and comblike extensions. Shark denticles (or scales) are toothlike and project out of the skin to form a complexly textured surface that interacts with free-stream flow. WebbSurface tension. The work which is required to increase the size of the surface of a phase is referred to as the surface tension. As a measure of work per unit area or force per wetted length, surface tension has the unit mN/m and is designated by the symbol σ (lower case sigma).. If the phase is solid, the equivalent term surface free energy is normally …

"WebbThe viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 7.1.1, have higher viscosities. We can measure viscosity by measuring the rate at which a metal ball falls ... " - Shark surface tension
