One gaul is defined as the resistance of an airway which, when air (of density 1.2 kg/m 3) flows along it at a rate of one cubic metre per second, causes a pressure drop of one pascal. The gaul has units of N·s 2 /m 8, or alternatively Pa·s 2 /m 6. It uses the same basic equation as its Imperial counterpart, but with slightly different ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
In engineering, the Moody chart or Moody diagram (also Stanton diagram) is a graph in non-dimensional form that relates the Darcy–Weisbach friction factor f D, Reynolds number Re, and surface roughness for fully developed flow in a circular pipe. It can be used to predict pressure drop or flow rate down such a pipe.
The key quantities are then the pressure drop along the pipe per unit length, Δp / L , and the volumetric flow rate. The flow rate can be converted to a mean flow velocity V by dividing by the wetted area of the flow (which equals the cross-sectional area of the pipe if the pipe is full of fluid).
To calculate the pressure drop in a given reactor, the following equation may be deduced: = + | |. This arrangement of the Ergun equation makes clear its close relationship to the simpler Kozeny-Carman equation, which describes laminar flow of fluids across packed beds via the first term on the right hand side.
The drop is an approximated unit of measure of volume, the amount dispensed as one drop from a dropper or drip chamber. It is often used in giving quantities of liquid drugs to patients, and occasionally in cooking and in organic synthesis. The abbreviations gt or gtt come from the Latin noun gutta ("drop").
Rhiannon (Welsh pronunciation: [r̥iˈan.ɔn]) is a major figure in Welsh mythology, appearing in the First Branch of the Mabinogi, and again in the Third Branch. Ronald Hutton called her "one of the great female personalities in World literature", adding that "there is in fact, nobody quite like her in previous human literature". [2]
Arianrhod (Welsh pronunciation: [arjˈanr̥ɔd]) is a figure in Welsh mythology who plays her most important role in the Fourth Branch of the Mabinogi.She is the daughter of Dôn [1] and the sister of Gwydion and Gilfaethwy; the Welsh Triads give her father as Beli Mawr. [2]
