AIR flowThe unreasonable design of guide vanes in the axial fan could have negative effects. In order to enhance the performance, the relationship between the air volume flow rate of the selected axial fan and geometric parameters of guide vanes is firstly analysed by DOE and CFD, and optimal...

Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured ...
Under the test condition (25 °C, 60% RH), WHR of each chip was 7·10−3 kg h−1 when air velocity was 1 m s−1 and air volume flow rate is 4.8 m3 h−1. Xu [14] also studied a TEC powered device through experiment. The results show that when current is 4 A and ...
If I have a tank of volume V, pressure P, and temperature T, what is the most effective way to determine the volume flow rate if I were to suddenly allow...
1d). To achieve an applied volume rate in the range of 400–600 l ha−1, in accordance to farmers’ practices (Marucco et al., 2019), ISO 02 nozzles at 0.4 MPa pressure, corresponding to a nominal nozzle flow rate of 0.91 l min−1, and a sprayer forward speed of 5.5 km h...
Airflow volume at 4500'/min = 220 CFM Upvote 0 Downvote Nov 27, 2002 #5 TD2K Chemical Jan 11, 2002 2,629 Sciguyjim, pressure drops for gases are a function of pressure and temperature (and composition but in this case, we've all agreed we are talking about air), neither of...
A decreasing uniformity index implies that the fan is subjected to distorted inlet conditions, which are known to negatively impact the volume flow rate through the fan (ξi < 1). It is interesting to note that the results are not simply mirrored for βw = −45° and βw = 45°. ...

Cough effectiveness is determined by a combination of volume of air expired and maximum expiratory airflow rate. Studies of cough sensitivity identify cough thresholds based on at least 2 or 5-cough re-accelerations to a stimulus, however, to date no study has examined the interplay between the...
