  2. Buoyancy - Wikipedia

    en.wikipedia.org/wiki/Buoyancy

    An object whose weight exceeds its buoyancy tends to sink. Calculation of the upwards force on a submerged object during its accelerating period cannot be done by the Archimedes principle alone; it is necessary to consider dynamics of an object involving buoyancy. Once it fully sinks to the floor of the fluid or rises to the surface and settles ...

  3. Convection - Wikipedia

    en.wikipedia.org/wiki/Convection

    In a column of fluid, pressure increases with depth from the weight of the overlying fluid. The pressure at the bottom of a submerged object then exceeds that at the top, resulting in a net upward buoyancy force equal to the weight of the displaced fluid. Objects of higher density than that of the displaced fluid then sink.

  5. Submerged specific gravity - Wikipedia

    en.wikipedia.org/wiki/Submerged_specific_gravity

    Submerged specific gravity is a dimensionless measure of an object's buoyancy when immersed in a fluid.It can be expressed in terms of the equation = where stands for "submerged specific gravity", is the density of the object, and is the density of the fluid.

  6. Water clarity - Wikipedia

    en.wikipedia.org/wiki/Water_clarity

    A diver enters crystal clear water in Lake Huron. Water clarity is a descriptive term for how deeply visible light penetrates through water. In addition to light penetration, the term water clarity is also often used to describe underwater visibility.

  7. Physical coefficient - Wikipedia

    en.wikipedia.org/wiki/Physical_coefficient

    Physical coefficient is an important number that characterizes some physical property of a technical or scientific object under specified conditions. [1] A coefficient also has a scientific reference which is the reliance on force.

  8. Surface tension - Wikipedia

    en.wikipedia.org/wiki/Surface_tension

    Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.

  9. Added mass - Wikipedia

    en.wikipedia.org/wiki/Added_mass

    The dimensionless added mass coefficient is the added mass divided by the displaced fluid mass – i.e. divided by the fluid density times the volume of the body. In general, the added mass is a second-order tensor , relating the fluid acceleration vector to the resulting force vector on the body.
