this is the minimum velocity that will allow a body to release itself from the grips of the gravitational pull of another body and travel to infinity without falling back. So…
Hello guys, I am really new in OpenFoam and i really need some help. I would like to know how to calculate the gradient of pressure and velocity in the same boundary condition? Thanks in advance September 28, 2011, 09:46 #2 drrbradford Member Daniel Join Date: Apr 2010 Location:...

there are two main methods of producing lab–grown diamonds: the HTHP (high pressure/high temperature) process and the CVD (chemical vapor deposition) process. The first method attempts to emulate the conditions under which natural diamonds are formed, using,...

during the constriction must be the same. In accordance with the conservation of mass, the velocity of the fluid must increase in the constricted volume, and thus, the kinetic energy also increases. Total energy cannot change, so pressure must decrease to balance out the increase in kinetic ...
1.The Pressure Gauge Guide: If your pump comes with a pressure gauge (a handy tool with numbers), here’s how to use it: Read the Numbers:Check the recommended PSI range for your bike (usually found on the tire sidewall). As you pump, keep an eye on the gauge – it’ll show you...
An important clue is provided by the temperature dependence of thermal diffusivity, Dth, obtained from κ17 and specific heat26. As seen in Fig. 3a, it shows a minimum, both at zero pressure and at 3 MPa. Fig. 3: Bounds to thermal diffusivity. a Thermal diffusivity, Dth = κ/...
In fluid mechanics, why is pressure inversely proportional to velocity of the fluid? How to find the pressure at a depth of a fluid of variable density? Explain with a problem. How does gas exert pressure on its container? What is the pressure exerted on you due to water if you are swi...
