This means that a decline in mixed flows
amounts, respectively, to 8% and as much as 29%.
0 corresponding to a fully mixed flow
in the room, which is a general experience for an air distribution system with swirl diffusers.
impeller systems (Figure 1) operate on the principle of internal and external dilution of contaminated exhaust air with unconditioned, outside ambient air.
This situation has been changing rapidly, with continuing advances in mixed flow
impeller technology for use in roof exhaust systems.
Axial flow pumps have high specific speeds, 8,000 to 16,000 rpm; mixed flow
, intermediate specific speeds, 4,200 to 9,000; and radial flow, speeds below 4,000 rpm.
The policy response to the economically mixed flow
of immigrants in Central America, and especially of vulnerable persons, is the topic of Chapter 5.
The test rigs will help Flowserve ensure its new pump variants meet the requirements of ISO 9906, which specifies hydraulic performance tests of centrifugal, axial and mixed flow

Energy consumption for mixed flow
fans is about 25% lower than conventional centrifugal fans.
A ceiling-mounted textile terminal creates a fully mixed flow
in large areas of a room.
Alternatives that were considered and rejected also included vertical mixed flow
pumps and the Archimedes screw type, which called for an excessively high structural cost for the pump station.
