The type of service they are to be used for In a home PVC is used for the drains,the drain vents,main out going sewer line,water supply lines for a boiler/heating system or sprinkler systems. In a home CPCV is used to supply water to sinks,toilets, showers,hot water heater and exterior faucets... Because of the difference in usage there is also a difference in the wall thickness between the PVC pipe and CPVC pipe... So a 3/4 in PVC fitting will not match up to a 3/4 in CPVC pipe and vise versa...
Many definitions of exterior and interior lines of operations are given by military writers, but it will be sufficient to say that "Interior lines are those of an army centrally situated acting against divided hostile forces; exterior lines are those adopted by divided armies acting against a centrally placed opponent."
Flush the lines from a clean potable water supply
The distance between railway lines varies depending on the type of railway track and the country. 60 percent of railway lines in the world, however, use the 1,435 mm standard gauge.
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.

Cut off British supply lines
The name for the elevation difference between adjacent contour lines is the contour interval.
The difference between interior lines and exterior lines are thatInterior lines: Are the lines that are in the inside of the shape or whatever you are trying to find the interior of.Exterior Lines: Are the lines that are outside of the shape or whatever you are trying to find the exterior of.
vertical lines run from top to bottom, horizontal lines run from left to right the difference between the two is 90 degrees if you place vertical lines next to horizontal lines.
It would be the difference between the two darker lines, or index lines, and then divide the space in between with your difference.
The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
The transversal is the line that cuts the parallel line.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
The difference between intersecting and parallel lines is that, on a graph parallel lines do ont touch,cross or anything. THEY NEVER TOUCH. intersecting lines touch, or cross eachother.\
