Feb 11, 2008 · Dear All, I need your help with a present problem - I am a student pilot, and want to see the derivation for the dynamic pressure formula - which is 1/2PV^2 where P - Density, V …

Jan 1, 2019 · As dynamic increases the static pressure decreases. But why? Dynamic is measured parallel to the surface and static measured normal to the surface. And dynamic is …

Jun 5, 2011 · Participants generally agree on the use of the dynamic pressure equation for calculating pressure from water speed, but there is some confusion regarding unit conversions …

Jul 3, 2021 · Some participants assert that dynamic pressure is defined as half the product of density and the square of velocity, leading to a need for conversion into static pressure units. …

Mar 12, 2022 · We know that the definition of the pressure coefficient is C p = p p ∞ q ∞, where p is the pressure at a point, p ∞ is the ambient pressure (free-stream), and q ∞ is the free …

Dec 21, 2009 · The window is not being 'blown' in, it's being 'sucked out' The higher force, 'static air pressure; as compared to the lower pressure on the wind loading surface, caused by the …

Mar 30, 2008 · My fluid dynamics is rather weak and i was wondering if someone could please tell me how to calculate dynamic head of the flow in the a tube and how to calculate pressure drop …

May 26, 2018 · The discussion revolves around understanding static pressure in a water pipe system over a city, particularly in the context of varying elevations and the use of piezometers …

Mar 14, 2018 · The discussion revolves around calculating the pressure drop across an abrupt change in diameter in piping systems, specifically for water. Participants explore fluid …

Jan 4, 2010 · One participant proposes using the difference between dynamic and static pressures for the velocity calculation, assuming negligible compressibility effects. A later reply …
