downflow การใช้

• This downflow of air often brings a smell with it.
• The preferred and most modern type of WESP is a downflow tubular design.
• Its structure is massive and lobate, with lobe diameters expanding downflow from.
• Water to be treated can be applied intermittently or continuously over the media, via upflow or downflow.
• The initial downflow of air from an approaching storm produces a huge yellow wall of sand and clay that can temporarily reduce visibility to zero.
• Local pier scour begins when the downflow velocity near the stagnation point is strong enough to overcome the resistance to motion of the bed particles.
• He still describes the downflow as being the " percolating . " Goodrich's design could transform any standard coffee pot of the day into a stove-top percolator.
• The first US patent for a coffee percolator, which however still used a downflow method without rising steam and water, was issued to James Nason of Franklin, Massachusetts, in 1865.
• Some of the latest trickle filter technology involves aerated biofilters of plastic media in vessels using blowers to inject air at the bottom of the vessels, with either downflow or upflow of the wastewater.
• Forward chines also act as Leading edge root extensions ( LERX ) at low speeds and high angles of attack, generating a downflow over the inboard wing to reduce its angle of attack and delay the stall, and also generating vortices which provide additional lift.
• Afterwards, measurements of the spectral emission lines emitted in the ultraviolet wavelengths have shown a systematic red-shift . The Evershed effect is common to every spectral line formed at a temperature below 10 5 K; this fact would imply a constant downflow from the transition region towards the chromosphere.
