A pressure prism is a way of visually describing the variation of hydrostatic pressure within a volume of fluid. When variables of fluid density , depth, gravity , and other forces such as atmospheric pressure are charted, the resulting figure somewhat resembles a prism .
Water pouring puzzles (also called water jug problems, decanting problems, [1] [2] measuring puzzles, or Die Hard with a Vengeance puzzles) are a class of puzzle involving a finite collection of water jugs of known integer capacities (in terms of a liquid measure such as liters or gallons). Initially each jug contains a known integer volume of ...
Density is the substance's mass per unit volume, or total mass divided by total volume. [21] Specific volume is total volume divided by mass, or the inverse of density. [22] The volumetric flow rate or discharge is the volume of fluid which passes through a given surface per unit time.
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.
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.
A tidal prism is the volume of water in an estuary or inlet between mean high tide and mean low tide, [1] or the volume of water leaving an estuary at ebb tide. [ 2 ] The inter-tidal prism volume can be expressed by the relationship: P=H A , where H is the average tidal range and A is the average surface area of the basin. [ 3 ]
Hyperboloid of one sheet. Solid geometry or stereometry is the geometry of three-dimensional Euclidean space (3D space). [1] A solid figure is the region of 3D space bounded by a two-dimensional closed surface; for example, a solid ball consists of a sphere and its interior.
The corn gallon, or Winchester gallon, of about 268.8 cubic inches (≈ 4.405 L), The wine gallon, or Queen Anne's gallon, which was 231 cubic inches [54] (≈ 3.785 L), and; The ale gallon of 282 cubic inches (≈ 4.622 L). The corn or dry gallon is used
