Open pipes do not produce superior tone than closed (or stopped) pipes. Pipe organs produce extremely varied tonal qualities therefore different types of pipes are used to produce different tonal qualities, both stopped, open and variations thereof, i.e. "half covered."
The pipe organ is a keyboard instrument.
The instruments most similar to a pipe organ are:Flute (pipe organ has flute pipes of different lengths)Harmonium
(a) 1.2r (b) 0.9r (c) 0.6r (d) 0.3r
The keyboard instrument with pipes would be the humble pipe organ.

To determine if a valve is open or closed, you can visually inspect the position of the valve handle or lever. If the handle is parallel to the pipe, the valve is open. If the handle is perpendicular to the pipe, the valve is closed.
When the handle is in line with the pipe, the valve is open.
Pressure rises in the tube.
The open channel flow has a free or rather open surface whereas the pipe flow has a closed surface.
The open channel flow has a free surface whereas the pipe flow has a closed surface.
The members of the string family, from the highest to the lowest, are the violin, the viola, cello and bass. Without the strings you would no longer have an orchestra, you would have a band. The string family, as a unit, can play the very highest notes and the very lowest.
In a resonating pipe that is open at one end and closed at the other, standing waves are formed due to the combination of incident and reflected waves. This creates specific resonant frequencies at which the pipe vibrates strongly. The fundamental frequency for this type of pipe is when the wavelength is four times the length of the pipe.
To determine if a pool valve is open or closed, check the position of the valve handle. Typically, a valve handle that is aligned with the pipe indicates it is open, while a handle that is perpendicular to the pipe signifies it is closed. Additionally, you can observe the flow of water; if water is flowing through the system, the valve is likely open. In contrast, if there is no flow or pressure, the valve may be closed.
The position of the handle indicates the direction of the opening through the ball, IE. handle in line with pipe, valve is open, tangent to pipe, valve is closed.
The pipe organ was invented by the Greek Ctesibius.
