Sentence examples for measured average air from inspiring English sources
A sensor location correction factor is determined by comparing the air velocity and the measured average air velocity.
The measured average air velocities from the two methods match very well, especially in the range of 0.5 1.5 m/s (100 300 fpm).
Open image in new window Fig. 5 Measured average air velocities from the fixed-point traverse and the moving traverse, and the standard deviation of the measured air velocities from the fixed-point traverse method.
All the correction factors of the centerline air velocities to the average velocities for the 21 measuring locations were calculated using the ratios of the measured average air velocity to the measured centerline single-point air velocity (as shown in Fig. 6).
Measurement results demonstrate that differences in the measured average air velocities between the moving traverse method and the fixed-point traverse method exist at a cross section where the air velocity spans a wide range.
This method saves time when measuring average air velocity comparing to the fixed-point traverse, but it cannot yield the distribution of the air velocity.
The moving traverse method is the most frequently used technique to measure the average air velocity at a cross section.
We calculated three different time-varying exposure measures: the average air pollution in the prior 2 calendar years, the average air pollution in the prior 4 calendar years, and the cumulative average exposure.
The 3T model is physically unsound if the field scale average air temperature, measured at an arbitrarily chosen reference height, is used as input to the model.
Figure 5 shows the comparisons of the average air velocities measured from the fixed-point traverse and the moving traverse.
Specifically, the PM2.5 average air concentration (measured using a light scattering instrument, mean 1160 μg/m) showed an average increase of 1.67 msec (95% CI: 0.11 to 3.22) in the mean heart rate, for every 1 mg/m increase in the average PM2.5 concentration.
