Nov 21, 2009 · hi, i've read in a lot of places that the minimum speed fora body to "finish" a vertical circle is (rg)^0.5, but I've never understood why.. they assume the...

Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and …

May 31, 2010 · Can anyone explain to me how angular velocity (w) = 2pi(f) -->where f = frequency. This is not a homework question involving numbers. I'm reading a section on "the …

Oct 31, 2022 · The viscous force within a fluid will depend on the velocity gradient (aka shear rate) within the fluid. That does not mean that the viscosity is a function of velocity. Viscosity is …

May 17, 2025 · In that case, A and B are satellites of C, and when the three particles become collinear (distance between A and B is 10 m), A stops moving "towards B with velocity 5 m/s …

Aug 1, 2009 · I heard it would be possible to have zero instantanous velocity & non zero acceleration (I know the opposite situation where there is velocity (constant), but zero …

Dec 3, 2018 · The goal of this post is to present Bernoulli's equation, its derivation based on energy conservation, and interpretations based on both momentum and energy conservation, …

Oct 15, 2014 · The angular velocity ω is usually a scalar, rather than a vector quantity. The magnitude of the radial velocity is given as v = ω r, where r is the magnitude of the radius vector.

May 28, 2025 · The first is the velocity of wave propagation along the boundary between the material and air or space. That will be close to the speed of light, slowed down by the dielectric …

Jan 20, 2015 · A pito array measures pressure, so you need Bernoulli's equation to find the velocity, THEN you can use Q=VA to find flow rate. So yes, pressure definitely matters for fluid …
