Outside dimensions

Production and consumption of wood products and residues are measured ia various units, based on common usage and their metric equivalents (2—4). Pulpwood logs and fuelwood are commonly measured ia cords. A cord refers to a stacked pile of wood, with outside dimensions of 4 by 4 by 8 ft (1.22 by 1.22 by 2.44 m) and a volume of 128 ft (3.62 m ). The weight of a cord depends on density of wood and bark and on moisture content. In the United States, it can range from 1.3 to 1.7 short tons (1.2 to 1.5 metric tons), air dried.

In such cases, the group of busbars in each phase may be considered to be one large conductor and outside dimensions a and b as illustrated in Figure 28.8 measured for all calculations. 

Another common problem on moulding is voids. These occur when a moulding or extrudate cools and hardens rapidly on the surface. On further cooling the moulding or extrudate cannot shrink inward because the outside dimensions are fixed and therefore the molecules are pulled towards the surface of the product, generating internal voids. At the same time molecules in the inner... 

Conducted heat is that going in through cold store surfaces, tank sides, pipe insulation, etc. It is normally assumed to be constant and the outside temperature an average summer temperature, probably 25-2/°C for the UK, unless some other figure is known. Coldroom surfaces are measured on the outside dimensions and it is usual to calculate on the heat flow through the insulation only, ignoring other construction materials, since their thermal resistance is small. 

Concentricity Term to describe two circles or cylindrical shapes having a common center and common axis, such as the inside or outside diameters of a barrel or outside diameters of the surface and bearing surfaces of a screw. Deviation from concentricity is referred to as runout. Also refers to the relationship of all inside dimensions to all outside dimensions usually expressed in thousands of inch or millimeter FIM (full indicator movement). Deviation from concentricity is usually referred to as a runout. The concentricity should allow for the maximum part tolerance. The geometry of the part should help indicate the tolerance applied. 

A 50 lb scatter-type bomb developed by the US is identical with the intensive type as far as outside dimensions are concerned. Incendiary material to be scattered consists of either cotton-waste balls impregnated with inflammable materials, such as turpentine or CS2, or gelled oil held in small celluloid containers. When the bomb lands, ignition and ejection of the units are effected by an explosion of Black Powder in the nose...

Although they are rarely needed, formulas in terms of outside dimensions, say Dol may be derived from the given ones by substitution of D0 — 2t for D. For the 2 1 ellipsoidal head, for instance,... 

This memory effect can cause dimensions to change. Outside dimensions can increase while internal dimensions will decrease. 

A fireproof safe is constructed of loosely packed asbestos contained between thin sheets of stainless steel. The safe is built in the form of a cube with inside and outside dimensions of 0.5 and 1.0 m. If the safe is initially uniform in temperature at 30°C and the outside is suddenly exposed to a convection environment at 600°C, h = 100 W/m2 °C, calculate the time required for the inside temperature to reach 150°C. Assume the inside surface is insulated, and neglect the resistance and capacitance of the stainless steel. Take the properties of asbestos as k = 0.16 W/m °C, a = 3.5 x 10 7 m2/s. 

A condenser is to be designed to condense 1.3 kg/s of steam at atmospheric pressure. A square array of 1.25-cm-OD tubes is to be used with the outside tube walls maintained at 93°C. The spacing of the tubes is to be 1.9 cm between centers, and their length is 3 times the square dimension. How many tubes are required for the condenser, and what are the outside dimensions ... 

The clamping debars (rods) can be used to support the fixed and movable platens on which the mold is attached. They serve as equally loaded tension support members of the clamp when the mold is closed. The open distance between tie rods through which the mold must fit and eject molded parts sets up the maximum outside dimensions of the mold that can be used. Different designs are used to meet different...

The back pressure was measured for two different preconverter assemblies (all catalyzed) in a chassis dynamometer test [4-liter, 6-cylinder engine with port fuel injection (PFI)]. Both preconverters had identical outside dimensions and catalyst loading but different cell structures. The back pressure, measured with the aid of H2O monometers, is summarized in Table 20. The differences in back pressure across the two preconverters are attributed to both the back pressure parameter and the frictional drag of catalyzed... 

A common joint design for clay pipe, one which the pipe manufacturer will probably try to sell, is a "pressure joint." For this kind of joint an elastomeric or flexible collar is set into, and usually cemented to, the inside of the bell. The inside dimension of the collar is smaller than the outside dimension of the spigot, so when the spigot is seated in the bell the collar squeezes tightly against... 

Strength Resistance of a material against a deformation caused by forces acting on it from outside. Dimension N/mm2 (MPa), q.v. bond strength. 

For hazardous materials not requiring placarding, identification numbers may be displayed on a white square-on-point configuration having the same outside dimensions as those prescribed for authorized placards. 

The size of CT closures is specified by the nominal outside dimension of the container opening in millimeters, plus a number that represents the style of finish. Both container and closure finishes are standardized so that, at least in theory, a closure of a given size and style should fit any bottle of that same size and style, from any manufacturer. U.S. closure standards have been established by the Closure Manufacturers Association, standards for glass bottles by the Glass Packaging Institute, and for plastic bottles by ASTM International (Fig. 11.8). Common closure diameters are 22-120 mm.
