Actual cubic feet per minute (ACFM) is a unit of volumetric flow. It is commonly used by manufacturers of blowers and compressors. [1] This is the actual gas delivery with reference to inlet conditions, whereas cubic foot per minute (CFM) is an unqualified term and should only be used in general and never accepted as a specific definition without explanation.
Standard cubic feet per minute (SCFM) is the molar flow rate of a gas expressed as a volumetric flow at a "standardized" temperature and pressure thus representing a fixed number of moles of gas regardless of composition and actual flow conditions.
The 2023 Mercedes-Benz S580e has the longest electric range of any plug-in hybrid we've tested on our 75-mph real-world route. The $120,000-plus sedan went 58 miles in EV mode, exceeding its ...
On 1 December 2010, Airbus launched the A320neo family (neo for New Engine Option) with 500 nmi (930 km; 580 mi) more range and 15% better fuel efficiency, thanks to new CFM International LEAP-1A or Pratt & Whitney PW1000G engines and large sharklets. [17]
Fitted with CFM International LEAP-1A or Pratt & Whitney PW1100G-JM engines, Airbus advertises a 20% increase in fuel efficiency per passenger, with 500 nautical miles (930 km; 580 mi) more range, or 2 tonnes (4,400 lb) more of payload.
[3] The Trent 500 is essentially a scaled Trent 800 , with a 2.47 m (97 in) fan with 26 unswept blades like the Trent 700 . The IP and HP compressors and scaled-down by 20% from the Trent 892, while the turbines are scaled-down by 90% and are made of single crystal CMSX-4 alloy with thermal barrier coatings .
The clean air delivery rate (CADR) is a figure of merit that is the cubic feet per minute (CFM) of air that has had all the particles of a given size distribution removed. For air filters that have air flowing through them, it is the fraction of particles (of a particular size distribution) that have been removed from the air, multiplied by the ...
