• Upping the efficiency of pumps and fans
  of equations called affinity laws. These laws, for centrifugal pumps and fans, relate how changes in speed or geometry affect capacity or power consumption. Q2 /Q1 = N2 /N1,. P2 /P1 = (N2 /N1) 2 , and. H2 /H1 = (N2 /N1) 3 ,. where N = fan speed, rpm; Q = flow, cfm; P = pressure, static in. H2O; and H...
• What Is The Correct Type Of Fan: Axial, Radial, Diagonal? (.pdf)
  Fans are as varied in their construction as they are in their applications. These "air-donors" are primarily differentiated according the physical principle of the transfer of energy to the gas medium. Depending on the design, each fan is suitable for a number of different uses. In this article we...
• Cutting Design Costs
  took place at AcoustiFLO, LLC, a specialist. in custom fan engineering in the U.S. For an efficient new centrifugal fan. module that could drop into packaged air handlers, the company's engi-. neers used CFD software to evaluate the interaction between the fan's. diffuser and impeller in many...
• Nuts to you -- I/O System Smooths The Move To Ethernet Controls For Walnut Dryers
  double-wide 66-in.-diameter centrifugal fans and two 60-hp motors provide dry air while two direct-fired 10 million-Btu gas burners heat the air to 110°F. Applied Instrumentation.

• FEA Update
  is performing as it is, which allows rapid design improvements. Wind-tunnel tests in this case were done over a range of flow rates at a fan speed of 2,000 rpm and standard atmospheric conditions. The Reynolds number, based on a 110-mm fan diameter and blade tip speed, is 1.2 X 10 . Blades are thin, cambered...
