Velocity, rate

Computed Maximum Pressure (CMP). Value of max pressure computed by means of interior ballistic formulas. It will be developed when a new gun of a particular type is fired under standard conditions with a propelling charge which will give to the projectile its rated muzzle velocity Rated Maximum Pressure (RMP). Value of max pressure specified in the proplnt specifications as the upper limit of avg pressure which may be developed by an acceptable proplnt in the form of propelling charges which will impart the specified muzzle velocity to the specified projectile. Normally about 2000psi.above the computed max pressure, subject to determination at the time of development...

Liquid face velocity rates (flow rates) for organic removal are usually less than 1 gpm/cu ft, but for chlorine are typically 2 to 3 gpm/cu ft.

Velocity—rate, v, activity, d P ldl, —d[S /dt—is how fast an enzyme converts substrate to product, the amount of substrate consumed, or product formed per unit time. Units are micromoles per minute (pmol/min) = units. 

The mathematical model developed to describe the nitric acid absorption process isdiscussed in detail in Section G.2. It uses a tray-by-tray approach that incorporates reaction-mass balance corrections and heat balance calculations. Tray efficiency calculations are also included in the model, the efficiency being a function of the tray geometry and gas velocity. Rate equations and other data specific to the nitric acid/nitrous gas system are applied. 

As the oil flows within its designated cross-section area through the horizontal vessel, free water droplets form and begin to drop at a terminal velocity rate. The Vessize program calculates this terminal velocity VTWO. As discussed previously in the oil dehydration section, the Stokes law settling equation is used for the water droplet fall rate VTWO.

Figure 8-4 Michael is-Menten curve relating velocity (rate) of an enzyme-catalyzed reaction to substrate concentration. The value of Km is given by the substrate concentration at which one half of the maximum velocity is obtained.

Solid-liquid separation systems generally consist of four stages including pretreatment, solid concentration in thickeners, solid separation in filters or centrifuges, and post-treatment by expression and washing operations. There are different types of SLS equipment served for different functions in relation to the four stages. Product specification, characteristics of solid-liquid suspension, solid settling velocity, rate of cake... 

At any given concentration, the initial velocity rate (Vg) is proportional to the enzyme concentration so the term Vg can be used as a measure of the enzyme concentration provided certain precautions are taken. One should be aware of the variability of these reaction constants with pH, temperature, and ionic strength. Likewise, conditions for substrate concentration should be selected to guarantee no interference with the reaction rate. Usually, the concentration of the substrate is chosen to be well above the value to ensure acceptable conditions (H3). As a side issue, it should be noted that substrates with a free N-terminal are 10 to 100 times more soluble than the corresponding benzoyl derivatives CTIO). Finally, one should always report the conditions under which the assay was run to allow comparison with other laboratories. 

Comparison of hyperbolic and sigmoidal enzyme kinetics. The plot of velocity, rate of reaction, versus concentration of substrate or activator shows the response of a hyperbolic (Michaelis-Menten) reaction in black. The response of a sigmoidal reaction is shown by the purple curve. The shaded area indicates the range of physiological concentrations of substrate or activator. 

Two common explosive materials are Primacord and Detasheet. PETN is the explosive core of Primacord, where it develops a velocity rate of 6,400 metres per second. Primacord is insensitive to friction and ordinary shock, hut may be exploded by rifle fire. It also detonates sympathetically with the detonation of an adjacent high explosive. Odours from Primacord thermostated at 60° C were tested and the organic compounds detected confirmed the presence of only PETN as shown in Figure 10. 

FSTN Tikis is used in detonating cord. It is one of the most powerful military exiklosivea, almost equal to nrtroglycerine and RDX. In deto3iattng < rd, PETK has a velocity rate of... 

II, but one quantitative analysis of such patterns has been developed since then. A sequential mechanism with two substrates has an initial velocity rate equation ... 

Note that these rules correctly predict that in a two-substrate case the only sequential mechanism in which a term is missing from the denominator is an ordered one in which the first substrate addition is in rapid equilibrium. Rapid equilibrium binding in a random mechanism does not change the initial velocity rate equation (Rule 1), since both substrates can add in the second position. These rules can easily be generalized for cases with four or more substrates.
