Volume mean

It is easy to see that combining uncertainties in this way overestimates the total uncertainty. Adding the uncertainty for the first delivery to that of the second delivery assumes that both volumes are either greater than 9.992 mL or less than 9.992 mL. At the other extreme, we might assume that the two deliveries will always be on opposite sides of the pipet s mean volume. In this case we subtract the uncertainties for the two deliveries,... 

The mean volume (mass diameter) is the arithmetic mean diameter of all the particle volumes or masses forming the entire population and, for spherical particles, can be expressed as in equation 2 ... 

Standardisation. Pipette 10.0 mL of the sodium tetraphenylborate solution into a 250 mL beaker and add 90 mL water, 2.5 mL 0.1 M nitric acid, 1.0 mL iron(III) nitrate solution, and 10.0 mL sodium thiocyanate solution. Without delay stir the solution mechanically, then slowly add from a burette 10 drops of mercury(II) nitrate solution. Continue the titration by adding the mercury(II) nitrate solution at a rate of 1-2 drops per second until the colour of the indicator is temporarily discharged. Continue the titration more slowly, but maintain the rapid state of stirring. The end point is arbitrarily defined as the point when the indicator colour is discharged and fails to reappear for 1 minute. Perform at least three titrations, and calculate the mean volume of mercury(II) nitrate solution equivalent to 10.0 mL of the sodium tetraphenylborate solution. 

In total, 550 analyses were conducted from samples taken at this site. These data indicate that only 5.8 percent of the 10.9 acres contaminated represented the road surfaces originally sprayed. The remaining surface contamination probably resulted from dispersion by wind, vehicular traffic, runoff, etc. The total TCDD sprayed was probably about 340 grams, with 74 percent still on the areas sprayed. Mean, volume weighted, TCDD concentrations in the sprayed and dispersed areas were 469 and 31 ppb, respectively. Concentrations in individual composite samples collected from sprayed areas ranged up to 1,800 ppb. About 90 percent of the TCDD was contained in 13 percent of the soil volume. 

For unpremixed feed streams, the mean volume fraction is defined in terms of the mean entering flow rates as... 

Therefore, it follows that the mean volume increases linearly with granulation time. From Eq. (52) we see that the size distribution is uniquely defined by a dimensionless size V/V, and in that sense it is self-similar. In order to compare with the experimental data, it is necessary to transform the size attribute from volume to diameter. From Eq. (52) it can be shown that (K3)... 

Clearly the granule size distribution is self-preserving in 1 Vt/V(t). Further, combining Eqs. (50), (64), and (68) results expression for the mean volume the reduced size in the following...

Table 9.7 shows the results of the calculations of average parameters of PBU/P for isotropic DRP, fulfilled by Serra [134] and Meijering [152], Serra used VD-method while Meijering used the Johnson-Mehl s (JM) statistical model [150] of simultaneous growth of crystals until the total filling of the whole free space was accomplished. The parameter Nv in the table is the number of PBUs in a unit of system volume, thus Nv 1 is the mean volume of a single PBU, which is related to the relative density of the packing (1—e) with an interrelation... 

Different components of the mixed phase occupy different volumes of space. To describe this quantitatively, we introduce the volume fraction of normal quark matter as follows X sc = Vnq/V (notation Xb means volume fraction of phase A in a mixture with phase B). Then, the volume fraction of the 2SC phase is given by X2nq = (1 — X.2sc)- From the definition, it is clear that 0[Pg.236]

Humphrey and Seal9 (U.S.A.) reported in 1959 detailed experiments on the ECT of sarcoma-180 tumors in nearly 500 mice. In a typical experiment, 18 test animals and 18 control animals were used the ECT was done with 3 ma current, at 6 V for 3 hours a day, for 24 days. They observed that after such a lengthy treatment, the mean volume of test tumors was about 15% of the mean tumor volume of the control group seven mice showed complete tumor regression as a result of ECT. Total regression means that the tumor has decreased progressively in volume, hardened, dropped off, leaving a new skin surface at the former tumor site. 

Another mean size based on volume is the mean volume diameter d v. If all the particles are of diameter d v, then the total volume of particles is the same as in the mixture.

Now, we can calculate a mean volume element that a dye occupies in the zeolite crystal, and if we consider this volume element as a cube, we can calculate the length of the cube. If we use a 1 1 mixture of donor D and acceptor A, this length is approximately the mean distance between D and A ...
