3. Centrifugal pump - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_pump

   Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...

4. Pressure gradient - Wikipedia

   en.wikipedia.org/wiki/Pressure_gradient

   The horizontal pressure gradient is a two-dimensional vector resulting from the projection of the pressure gradient onto a local horizontal plane. Near the Earth's surface, this horizontal pressure gradient force is directed from higher toward lower pressure. Its particular orientation at any one time and place depends strongly on the weather ...

   Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.

6. Lists of physics equations - Wikipedia

   en.wikipedia.org/wiki/Lists_of_physics_equations

   In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.

7. Secondary flow - Wikipedia

   en.wikipedia.org/wiki/Secondary_flow

   There is a pressure gradient from the perimeter of the bowl or cup toward the center. This pressure gradient provides the centripetal force necessary for the circular motion of each parcel of water. The pressure gradient also accounts for a secondary flow of the boundary layer in the water flowing across the floor of the bowl or cup. The slower ...
