For a given outlet pressure , flow rates change depending on the inlet pressure as an arc of hyperbola in a plane parallel to ˙. Usually, Stodola's cone does not represent absolute flow rates and pressures, but rather maximum flow rates and pressures, with the maximum values of the diagram having in this case the value of 1.
English: This PDF displays the movements of the internal Conus docking cones within the Mir core module's forward docking hub over the lifetime of the station. Most Conus movements were made by cosmonauts during internal EVAs lasting approximately 20 minutes, as the Conus placement required removing one of four outer hatches exposing the pressurised hub to the vacuum of space.
A cone of depression is a circular area surrounding a well where groundwater levels are reduced from pumping. [1] [2] In an unconfined aquifer (water table), this is an actual depression of the water levels. In confined aquifers , the cone of depression is a reduction in the pressure head surrounding the pumped well.
Fluid flows through a length of pipe of varying diameter. To avoid undue aerodynamic drag, a Venturi tube typically has an entry cone of 30 degrees and an exit cone of 5 degrees. [1] Venturi tubes are often used in processes where permanent pressure loss is not tolerable and where maximum accuracy is needed in case of highly viscous liquids.
General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.

In 1956, Taylor showed that when a fluid forced into porous sheet of cone or wedge, a favorable longitudinal pressure gradient is set up in the direction of the flow inside the cone or wedge and the flow is rotational; this is in contrast in the vice versa case wherein the fluid is forced out of the cone or wedge sheet from inside in which case ...
Artist's rendering of a payload fairing being jettisoned An example of clamshell fairing of Falcon 9 during testing, 27 May 2013. A payload fairing is a nose cone used to protect a spacecraft payload against the impact of dynamic pressure and aerodynamic heating during launch through an atmosphere.
