Velocity, initial maximum

A plot of the rate constant, the initial velocity, the maximum velocity of a catalyzed reaction, or the ratio of an enzyme-catalyzed reaction (or the decadic logarithm of any of these quantities) as a function of the pH value of the solution, all other variables being held constant. See also pH Effects... 

For the simple case illustrated in Eq. 9-54, the pH dependence of the initial maximum velocity, the apparent Michaelis constant, and Vmax/ Km are given by Eqs. 9-55 to 9-57.

Temporal changes in the PSDF may also reflect conditions both within and outside the aquifer. For both storms, dmax reaches a maximum at the same time that TSS peaks, a reflection of maximum flow velocity. The maximum particle size decreases from 8 to 12 hours after rainfall, possibly indicating that an initial flush of water from one source is later followed by an influx from another source. The late flush of clay minerals for storm 2, seen both in the mineralogy and as an increase in N4,jin, indicates a newly accessed source of clay minerals. 

In fact, some droplets fall down with a continuously accelerated velocity v(z) = j2g(h - z), so that their density has not been distributed uniformly across the droplet layer they are denser on higher levels and sparser on lower ones in accordance with (3.81). This leads to velocity local maximum in the initial region like those in Figs. 1.14,A and 3.22 that disappear however in the main flow region.

Example 10 Response to Instantaneous Valve Closing Compute the wave speed and maximum pressure rise for instantaneous valve closing, with an initial velocity of 2,0 m/s, in a 4-in Schedule 40 steel pipe with elastic modulus 207 X 10 Pa, Repeat for a plastic pipe of the same dimensions, with E = 1.4 X 10 Pa. The liquid is water with P = 2.2 X 10 Pa and p = 1,000 kg/m. For the steel pipe, D = 102,3 mm, b = 6,02 mm, and the wave speed is... 

Sfo is the Stokes number based on initial nuclei diameter do [Adetayo et al.. Powder Tech., 82, 37 (1995)]. Extent (/cf), depends logarithmically on binder viscosity and inversely on agitation velocity. Maximum granule size depends hnearly on these variables. Also, (/cf ), has been observed to depend hnearly on liquid loading y. Therefore, the maximum granule size depends exponentially on liquid loading. Fig. 20-73 illustrates this normahzation of extent (/cf), for the drum granulation of hmestone and fertilizers. 

As was shown by Zhivov, the main difference in most of the equations for the jet trajectory is the value of the coefficient i)i. The differences in experimental data obtained by different authors are mainly due to the difficulties in the measurements of nonisothermal air jets supplied with low initial velocities (2-10 m/s). There is also a different understanding of the term air jet trajectory. Some authors mean the points with maximum velocity values, while others mean the centers of gravity of the cross-sections of the jet. 

Air throw The maximum distance from the outlet of an ATD to a plane tangential to the jet envelope and perpendicular to the initial jet section where the velocity is reduced to a predetermined level. 

Examination of equation 2.43 shows that the mass flux initially increases as concentration increases but then passes through a maximum and finally declines as velocity decreases due to hindered settling (Figure 2.8). 

As a vessel ruptures, its fragments accelerate rapidly to a maximum velocity. This value is the initial fragment velocity Vj. It is used to calculate either the range of fragment travel or, if collision with an obstacle occurs before maximum range is attained, impact velocity.
