initial velocity

in·i·tial ve·loc·i·ty

the rate of a reaction, for example, an enzyme-catalyzed reaction, at the early stages of the reaction such that the product(s) concentrations have not risen to a level to significantly affect the observable rate; typically, initial velocities are observed when less than 10% of the reaction's approach toward equilibrium has occurred.
Synonym(s): initial rate

when the angular velocity [omega] is higher, the required initial velocity [v.
It can be concluded that the lower polymer throughput rate, higher polymer melt initial temperature, higher air initial temperature, higher air initial velocity, smaller angle between slot and axis of the spinneret, smaller width of the die head, and larger width of the slot can all produce finer fibers.
In our design approach, we solved literal equations; equation (6) was solved for initial velocity, vi, as shown in equation (8).
Plot the initial velocity data (replicates should be shown as means [+ or -] standard deviation of the replicates).
Discrepancy in the initial velocity or mine mass, as well as range (due to changing cartridge temperature) corrections, is included in the program by replacing the original data.
54 fps, at discharge opening) caused mixing and reduced the ability of the personalized flow with lower initial velocity (0.
Because the initial conditions at the fan (such as the initial velocity or initial duct size) must be selected to begin the static regain method, it has a large number of solutions, like the other methods presented.
What will be the initial velocity of the 2-kg pumpkin when it leaves the trebuchet?
The upper parts of Figure 7 show how the relationship changes with the quantity and diameter of the nozzles, and the initial velocity and the height of the nozzle respectively.
This is due to fact their higher initial velocity allows them to reach the target more quickly than slower bullets, so that gravity has less time to pull them down, and also because lighter bullets typically have more streamlined design, which allows them fly more efficiently with less susceptibility to air resistance than heavier bullets, which are typically more blunt-nosed and less aerodynamic.
Then the average force in an impact is mass times initial velocity squared, divided by twice the distance it takes to stop the object.
Consequently, to examine car crashes and insurance, initial velocity V0 may be found out.
