A pipe, esp. an organ pipe, whose tone is produced by the impinging of a current of air upon an edge, or lip, causing a wave motion in the air within; a mouth pipe; -- distinguished from reed pipe. Flue pipes are either open or closed (stopped at the distant end). The flute and flageolet are open pipes; a bottle acts as a closed pipe when one blows across the neck. The organ has both open and closed flue pipes, those of metal being usually round in section, and those of wood triangular or square.
organ pipe whose tone is produced by air passing across the sharp edge of a fissure or lip
A pipe which produces its sound by the action of air against the edge of the pipe mouth in combination with the resonance of a column of air within an open or closed pipe. One of three basic families of pipes: Flue, as just described. Reed pipes, which produce sound by the vibrations of a free or beating reed. Diaphone pipes (rarely used), which produce sound by intermittent bursts of air introduced into the pipe. The flue pipe family encompasses many different popular types of pipes, including various flute, diapason, and violin varieties. Flue pipes, unlike reed pipes, require a minimum of attention and care and will stay in tune for relatively long periods of time at a given temperature. For this reason flue pipes (usually violin and flute) were the main types used in smaller styles of coin pianos and orchestrions.
This kind of pipe can be made of metal or wood. The sound is produced when the wind flows through the foot of the pipe and flows out the mouth (the hole in the front of the pipe). The air hits the lip of the pipe and causes the column of air to vibrate. The length of this column of air which, in turn, determines the pitch of the sound. The pipe's length determines the size of the air column. For a diagram of a flue pipe, see the sound characteristics page. Most of the pipes on the organ are flue pipes. The others are reed pipes. There are several types of flue pipes: Principals, Flutes, and Strings.
Metal cylindrical pipe used to allow smoke and products of combustion from furnace, boiler, or hot water heater to exhaust into chimney and out of house.
The pipe connecting a closed burning appliance to the flue. Usually cast iron, stainless steel, or vitreous enamelled steel.
Airtight conduit constructed within a chimney using fireproof materials to carry away combustion gases and smoke occurring in a furnace or firebox.
In a pipe organ, a flue pipe is any pipe that is sounded by a fipple, similar to that in a whistle or a flute a bec, rather than by a beating reed, see reed pipe. Most of the pipes in a typical pipe organ are flue pipes; Smaller organs may have only flue pipes.
