Circumference/diameter

We use discrete time, a floor plan with 800 px x 600 px, and nodes represented by circumferences of 6px radius moving at a maximum speed of 2px/roimd. Approximating these values to meters, nodes are 70 cm diameter circumferences. From the circumference diameter it can be derived that a pixel is 5.83 cm and it can move up to 1.16 m/s in a 46.7 m x 35 m physical environment.

Radial density gradients in FCC and other large-diameter pneumatic transfer risers reflect gas—soHd maldistributions and reduce product yields. Cold-flow units are used to measure the transverse catalyst profiles as functions of gas velocity, catalyst flux, and inlet design. Impacts of measured flow distributions have been evaluated using a simple four lump kinetic model and assuming dispersed catalyst clusters where all the reactions are assumed to occur coupled with a continuous gas phase. A 3 wt % conversion advantage is determined for injection feed around the riser circumference as compared with an axial injection design (28).

Figure 12-9 shows on and off potentials that were measured around the circumference of a flat-bottomed tank 100 m in diameter. These values, however, give no information on the tank/soil potentials at the center of the container or at points away from the edge of the tank. In new tank constructions, long-life reference electrodes are therefore installed in the center of the base where the most positive potentials are found [15]. 

The thermal expansion and contraction of solids can also have safety implications. For a given material the amount of its linear expansion, or contraction, in one direction is directly related to temperature and its original size (i.e. length, diameter, circumference). Thus ... 

The equivalent diameter D,. in a dimpled jacket equals 0.66 m. the cross-sectional flow area equals 1.98 m." per foot of vessel circumference. 

The band structure of four concentric armchair tubules with 10, 20, 30, and 40 carbon atoms around their circumferences (external diameter 27.12 A) was calculated, where the tubules were positioned to minimize the energj for all bilayered pairs 17). In this case, the four-layered tubule remains metallic, similar to the behavior of two double-layered armchair nanotubes, except that tiny band splittings form. 

The vessel is a 15 ft high cylinder with a diameter of 16.25 ft constructed of half-in thick, type 304 stainless steel plate. Six outlet nozzles are uniformly spaced around the circumterence at the bottom, and six tapered inlet nozzles are uniformly spaced around the circumference of the water plenum at the top of the vessel. The primary water system PWS contains 40,000 gal of DjO 24,000 gal in the re tank and 16,000 gal in the piping system. Each of the six primary loi ted...

The k p scheme has been used also for the study of transport across junctions connecting tubes with different diameters through a region sandwiched by a pentagon-heptagon pair [25]. In Junctions systems, the conductance was predicted to exhibit a universal power-law dependence on the ratio of the circumference of two CNTs [26]. An intriguing dependence on the magnetic-field direction was predicted also [27]. These newer topics will be discussed elsewhere. 

Because the liquid tends to flow to the wall, and any that reaches it is reduced in effective contact possibilities, no large percentage (not over 10%) of the total liquid should enter the packing at the lop packing-vrall circumference, or within. 5-10% of the tower diameter from the tower wall. With this approach the bulk of the liquid starts down the tower somewhat away from the wall. 

Circular Circular pitch is the distance from a point on one tooth to the corresponding point on the next tooth measured along the pitch circle as shown in Figure 57.32. Its value is equal to the circumference of the pitch circle divided by the number of teeth in the gear. While most common-size gears are based on diametric pitch, large-diameter gears are frequently made to circular pitch dimensions. 

Diametric pitch is a whole number used to specify the ratio of the number of teeth in a gear to its pitch diameter. Stated another way, it specifies the number of teeth in a gear per inch of pitch diameter. For each inch of pitch-circle diameter, there are pi (jr = 3.1416) inches of pitch-circle circumference. Therefore, the diametric pitch provides the number of teeth for each 3.1416 inches of circumference along the pitch circle. 

The pitch-circle diameter and the diametric pitch of a 4-inch pitch-circle diameter gear are illustrated in Figure 57.33. For this 4-inch gear, there are four 3.1416-inch circumference segments. Note that for a 3-inch gear, there are three 3.1416-inch segments. 

The mathematical relationship of the circular pitch to the pitch-circle circumference, number of teeth, and the pitch diameter is shown in the following equations ... 

C = Pitch circle circumference (jtD), inches D = Pitch diameter, inches N = Number of teeth p = Circular pitch, inches jr = pi (3.1416)...
