Air pressure combined with air duct leakage can lead to a loss of energy in a HVAC system and duct sealing solves issues of energy loss in the system. Signs of leaky or poorly performing air ducts include Utility bills in winter and summer months above average relative to rate fluctuation Spaces or rooms that are difficult to heat or cool Duct location in an attic, attached garage, leaky floor cavity, crawl space or unheated basement.

Unreferenced date December 2009 Unsourced image removed Image bypassduct.gif thumb right 240px Typical bypass duct, in a high bypass ratio turbofan A bypass duct is an wikt annular annular passage that allows some of a turbofan turbofan s airflow to bypass the engine core, or gas generator . If the turbofan is unmixed, the bypass duct will terminate at the bypass nozzle. In mixed turbofans, the bypass duct leads to the cold chute of a forced mixer or cold mixer of an annular mixer. Some bypass ducts are unlined, so the bypass air must pass over a series of flange s, pipe material pipe s, etc associated with the engine core, which increases the bypass duct pressure loss. A lined bypass duct has a lower pressure loss, due to the streamlining effect of the inner wall introduced. Bypass ducts may be fitted with doors that allow the air to be diverted forward, providing reverse thrust . Air passing through an engine s core is not affected by this. This is common practice on high bypass ratio turbofans found on airliners today, such as the GE CF6 and GE90, Rolls Royce RB211 and Trent, Pratt & Whitney JT9D and 4000 etc. For a more detailed look at this issue, including consideration of different types of thrust reversal, see the reverse thrust thrust reversal page.

orphan date July 2010 An acoustic duct is a test facility used in acoustics . Anechoic chamber s are typically subject to a low frequency limit, governed by the length of the sound absorbing wedges employed to prevent reflections within the chamber. Test and measurement microphone calibration services are often required to be undertaken at frequencies where anechoic chambers cannot be used effectively. In this case, a plane wave acoustic duct with anechoic termination provides a practical alternative. Such a facility consists of a long duct , with a special low frequency sound source subwoofer at one end and very large acoustically absorbent wedges at the other end. The duct cross section dimensions are made sufficiently small compared to the wavelength at the frequencies of interest that sound can be assumed to propagate down the duct as a plane wave with no reflections from the sides. Acoustic ducts are most commonly used by National Measurement Institutes that specialise in acoustical measurement such as the National Physical Laboratory United Kingdom , who use them for measurement microphone calibration at low frequencies.
