The pipe's cross-sectional area has a number of applications in fluid dynamics, letting you calculate a pipe's flow rate or pressure drop. The measurement relates directly to the pipe's internal diameter. The factor relating the pipe's diameter and its area is pi, which is also the ratio...
A method of estimating the cross-sectional area of a molecule for use in the prediction of ion mobility gives gas phase interaction radii determination and cross-sectional algorithm computation to provide separation and characterization of structurally related isomers. More specifically, the invention ...
Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w. If the cutting plane is parallel to one of the two sets the sides, the cross-sectional area is instead given by l × h or w × h. If the cross-section is ...
Consider two copper wires. One has twice the cross-sectional area of the other. How do the resistances of these two wires compare? A. Both wires have the same resistance. B. The thicker wire has half the resistance of the shorter wire. C. The thicker wire has twice the resist...
A CAT scanner, however, uses a group of X rays to give a cross-sectional(横截面)view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information form each direction and ...
To get the maximum carrying capacity, you need a simple formula. Some practical cases are not easy to calculate. This is due to the rise in temperature and cross sectional area. Other things also determine the current carrying capacity of the trace. These things may include vias, components,...
Computing the projected cross-sectional area along those directions Interpolating the data onto all intermediate directions Extracting this data To start, we create a very particular kind of geometry, as shown in the figure below. This geometry looks like a mesh of a quarter-sphere, and is create...
Topographic maps use contour lines to show the elevation of an area. These lines have rules: they cannot cross, and they form circles around hills or depressions. Explore topographic and geologic maps, and learn how to read their contour lines, geologic markings, and colors. ...
The only practical way to do this is to add some sort of large rocket engine that fires right before impact. One way to make a bunker buster heavier while maintaining a narrow cross-sectional area is to use a metal that is heavier than steel. Lead is heavier, but it is so soft that...
Analysts implement a cross-sectional analysis to identify special characteristics within a group of comparable organizations, rather than to establish relationships. Often cross-sectional analysis will emphasize a particular area, such as a company'swar chest, to expose hidden areas of strength and weakn...
