Polythene is passed through a rectangular slit die 5 mm wide, I mm deep at a rate of 0.7 X 10 w /s. If the time taken is 1 second, calculate the natural time and comment on its meaning. 

A second calculation was done for a two-layer tubule using density functional theory in the local density approximation to establish the optimum interlayer distance between an inner (5,5) armchair tubule and an outer armchair (10,10) tubule. The result of this calculation yielded a 3.39 A interlayer separation... 

Accordingly, we will swap orbitals 6 and 13. We define the active space to comprise these orbitals by using the Gues =Alter keyword in the route section for the first job step in our second calculation series ... 

Here is an example of an input file containing two job steps in which the second calculation depends upon and uses the results of the first job step ... 

Temperature decrease of the mud 1.19°C = 2.15°F (second calculation is probably more correct)... 

The second calculation is on the production costs themselves. We can discriminate three major parts ... 

There is some debate about what controls the magnesium concentration in seawater. The main input is rivers. The main removal is by hydrothermal processes (the concentration of Mg in hot vent solutions is essentially zero). First, calculate the residence time of water in the ocean due to (1) river input and (2) hydro-thermal circulation. Second, calculate the residence time of magnesium in seawater with respect to these two processes. Third, draw a sketch to show this box model calculation schematically. You can assume that uncertainties in river input and hydrothermal circulation are 5% and 10%, respectively. What does this tell you about controls on the magnesium concentration Do these calculations support the input/removal balance proposed above Do any questions come to mind Volume of ocean = 1.4 x 10 L River input = 3.2 x lO L/yr Hydrothermal circulation = 1.0 x 10 L/yr Mg concentration in river water = 1.7 X 10 M Mg concentration in seawater = 0.053 M.

C15-0088. Fireflies flash at a rate that depends on the temperature. At 29 °C, the average rate is 3.3 flashes every 10 seconds, whereas at 23 °C, the average rate falls to 2.7 flashes every 10 seconds. Calculate the energy of activation for the flashing process. 

We carried out a second calculation for BeH at an internuclear distance of 2.67 a.u. corresponding to the minimum of energy.The mean magnetic susceptibility x obtained value, which is equal to -0,86.lO erg.G. mol V, agrees more closely to the value calculated by Fowler and Steiner [5], at the same internuclear distance,which is equal to -0.50 10 erg. G. mol F... 

In a second calculation, we trace the same path while maintaining the fluid in equilibrium with the calcite. To do so, we enter the command... 

In a second calculation, we assume benzene not only biodegrades, but sorbs to organic matter in the aquifer... 

In a second calculation, we model the reaction path taken when the minerals, once precipitated, cannot redissolve into the fluid. In this model, the solutes in seawater fractionate into the minerals as they precipitate, irreversibly altering the fluid composition. As discussed in Chapter 2, we set up such a model using the flow-through configuration. The procedure is... 

For the second sample, parallel calculations give 0.001200 mol NaCsHs, 0.093 g C4H8, x =1.1. There is rounding error in this second calculation because it is limited to two significant figures. The best answer is from the first run x -1.02 or 1. The formula is NaC5H5(THF),. 

SAQ 9.5 A solution of beetroot juice is strongly coloured. The incident beam shining through it I0 emits 4 x 1010 photons per second, and the emergent beam emits 109 photons per second. Calculate the absorbance of the solution. 

Why did the posterior probability increase so much the second time One reason was that the prior probability was considerably higher in the second calculation than in the first (27% versus 2%), based on the fact that the first test yielded positive results. Another reason was that the specificity of the second test was quite high (98%), which markedly reduced the false-positive error rate and therefore increased the positive predictive value. 

First, find the sale price. Using the shortcut, the tent will cost 100 - 25 = 75% of the regular price 0.75 x 139.95 = 104.96, rounded to the nearest cent. Second, calculate the sales tax, which is based on the sale price, and add it to the sale price 0.07 x 104.96 = 7.35, rounded to the nearest cent. The total price is therefore 104.96+ 7.35 = 112.31.

Two variables, the concentration of LSD-25 in the nebulizer and the inspiration time were varied. Experiments indicated that this technique of changing the response in this type of experiment has some validity. Table II summarizes the experiments. These preliminary experiments indicated to the writer tiiat the response of a well-tested subject was fairly regular since with a given dose of40,000 mcg-seconds (calculated administration of 56 meg) severe... 

No reactor can produce yields of products beyond those predicted by chemical equilibrium, and the second calculation anyone should perform on a process (after calculating the adiabatic temperature for safety considerations) is the equilibrium composition. 

Activity measurements. Activity and selectivity measurements were performed at 10 psig in a 14-mm internal diameter glass fluid bed reactor using 25 grams of 90 to 38 micron catalyst particles. A reactant mixture of approximately 18 volume % 02 7 volume X NH3 and 7 volume % CH3OH and the balance of helium was fed to the catalyst, and temperature and contact time were varied to find the optimum yield of HCN. Optimum reaction temperatures were found to range from 425° to 475°C with contact times of 3 to 5 seconds (calculated at STP>. Fixed bed reactor studies produced similar results. The yields reported in this paper are based on carbon fed, unless otherwise noted. More details on catalyst performance can be found in our patents (7,8). 

The stability factors were recalculated, and the pitted or mylonitized vitrinite was treated as semifusinite with two-thirds of it being assigned to inerts. Figure 6 shows the relation of the predicted stabilities to the stabilities actually obtained on the coke. Two sets of points are shown, one indicating the position of the stabilities as first calculated and the other the stabilities after re-evaluating the vitrinite. The second calculation is a considerable improvement in the relation of predicted to actual stabilities. The complete data upon which these calculations were made are shown in Table V, while other data pertinent to the evaluation of the samples coked in the movable-wall oven are given in Table VI. The position of the coal represented by point 5 was not improved by recalculation. This coal gave an actual stability of 20.2. 

Second, calculate pseudoreduced temperature and psuedoreduced pressure.
