By the 1870s all houses were constructed with cast iron gutters and down pipes. The Victorian gutter was an ogee, 115 mm in width, that was fitted directly to the fascia boards eliminating the need for brackets. Square and half-round profiles were also available.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
The purpose of a downspout is to allow water from a gutter to reach the ground without dripping or splashing down the building structure. Downspouts are usually vertical and usually extend down to ground level , although may be routed at an angle to avoid architectural features and may discharge onto an intermediate roof.
For a fully filled duct or pipe whose cross-section is a convex regular polygon, the hydraulic diameter is equivalent to the diameter of a circle inscribed within the wetted perimeter. This can be seen as follows: The N {\displaystyle N} -sided regular polygon is a union of N {\displaystyle N} triangles, each of height D / 2 {\displaystyle D/2 ...
The bodies of fittings for pipe and tubing are often the same base material as the pipe or tubing connected: copper, steel, PVC, CPVC, or ABS. Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the ...
During the IPS period, pipes were cast in halves and welded together, and pipe sizes referred to the inside diameters. [1] The inside diameters under IPS were roughly the same as the more modern Ductile Iron Pipe Standard (DIPS) and Nominal Pipe Size (NPS) Standards, and some of the wall thicknesses were also retained with a different ...
Pipe sizes can be confusing because the terminology may relate to historical dimensions. For example, a half-inch iron pipe does not have any dimension that is a half inch. Initially, a half inch pipe did have an inner diameter of 1 ⁄ 2 inch (13 mm)—but it also had thick walls. As technology improved, thinner walls became possible, but the ...
