An air rate meter according to the vortex velocity principle has a measuring tube, in which at least one disturbance member is located for the purpose of vortex formation and in which at least one pressure transducer for generating vortex pulses is provided; the pressure transducer is followed ...
for compressing air from some initial intake pressure (usually atmospheric) to a higher pressure. Compressors (as well as other fluid machines) can be classified into two main types, depending on the air or fluid action: (1) thepositive-displacementtype and (2) the velocity, ordynamic, type...
While the primary policy scenario results in a widening of the air pollution exposure disparity for racial/ethnic minorities, further reductions in racial/ethnic minority exposures are in principle achievable while still meeting the same CO2emissions reductions. The comparison between the Cap 50% scenari...
(round) jets can be referred to. The principle is to generate such high air velocity that a shield against pressure difference, temperature difference, andwind velocityis sustained. However, it is not possible to have complete separation by an air curtain. The main reason is that the jet en...

In the optical automatic detection instrument for defects of glass substrate, the principle of the air flotation is shown in Fig. 1: The air-flotation plate is provided with positive pressured air injection holes and negative pressured vacuum holes, which are arranged in array. The air ejected ...
Later fuel spray nozzles utilize the airspray principle that employs high velocity air instead of high velocity fuel to cause atomization. This method allows atomization at low fuel flow rates (provided sufficient air velocity exists) thus providing an advantage over the pressure jet atomizer by ...

1. The carrier gas needs to pass at a sufficiently low velocity. The solid particulates, which have higher density than the surrounding gas, settle on the base of the chamber through gravity influence, and then be collected and removed by dust hoppers in the bottom. Uniform flow within the ...
