In all measured cases for both parallel and series FPTUs, the downstream static pressure
did not exceed 0.10 in.
Then he programmed the VFDs with parameters for energy-efficient operations, including maintaining a static pressure
of 1.5 in.
Tables 1 and 2 show that the damage strength of concrete is the largest for specimens subjected to dynamic pressure, followed closely by the strength of specimens under static pressure
. The damage strength is much less for specimens subjected to static and dynamic tensile loading.
The total pressure test points and static pressure
test points are shown in Figure 6.
As shown in Figure 7, it is found that when the [h.sub.t] was less than a certain critical equivalent height [h.sub.tc], the difference of the static pressure
did not change significantly, and the slope of the curve varied gradually.
Without the PSV, the building pump is responsible for adding pressure to overcome friction loss through the piping and coils as well as additional lift pressure to circulate water above the elevation of the plant static pressure
. When the PSV is installed, the PSV resistance takes the place of the required lift pressure, and no additional head is introduced to the system, so there is no increase in energy consumption.
Available in 60mm, 80mm, 92mm, and 120mm frame sizes, these 12V, 24V, and 48V fans can provide CFM and static pressure
values up to three times those of competing fans.
Although the series fan arrangement may be somewhat unusual it seems to have merit in reducing the overall system static pressure
required to meet the need of the most demanding far terminals.
The static pressure
at point A was higher than at point B, 13 mmHg vs.
While static pressure
is simulated, minimally one current source is set at the moments of static pressure
Unlike most other PC fans in the market, Corsair Air Series fans are offered in airflow and static pressure
models, each specifically optimized for specific PC cooling roles.
