Arrays VelocityX[], VelocityY[], and VelocityZ[] are one-dimensional arrays of double type. Elements, VelocityX[0], VelocityY[0], and VelocityZ[0] express the component of velocity of the 0th particle in x, y, and z directions, respectively. In this case, all the velocity components...
The aerodynamic drag force is given by the formula [23] 𝐹𝐷𝐴=𝐶𝐷𝐴𝐴𝜌𝑣2𝑟2FDA=CDAAρvr22 (4) In the event that the force of gravity balances with the force of aerodynamic resistance, the particle is suspended in the air stream and there is no inertia force due...
Velocity, like position, is a vector quantity which means that it has both a magnitude (how much) and a direction. The direction of the object's velocity is determined with respect to a chosen reference system and can be one-, two-, or three-dimensional....
Mattheij, in Studies in Mathematics and Its Applications, 2002 2.4 Dimensional analysis In order to examine the behaviour of the momentum and the energy equations, in particular to determine whether diffusion or convection prevails, we make the equations dimensionless. Let us rewrite them as new ...
Blood flow velocity in the cerebral perforating arteries can be quantified in a two-dimensional plane with phase contrast magnetic imaging (2D PC-MRI). The velocity pulsatility index (PI) can inform on the stiffness of these perforating arteries, which is related to several cerebrovascular diseases...

Create a formula for a motion equation (x vs. t) that is one dimensional motion (along the x-axis) with constant acceleration (that may or may not be zero). Given: t = time a = acceleration v(t) = velocity at t v_0 = initial value of velocity ...
Note that the diffusion is regarded as one dimensional. When both the molecular and viscous flows exist, the total mass transfer rate is expressed by the sum of these two flow rates: (18.89)Ji=−1RˆT(ετdp232μpidpdy+DK,idpidy). The total (p) and the partial pressure of ...
