Information about the airflow development in pipes in the entrance region is still not thoroughly investigated due to the complexity and restricted access for experiments. However, the reproduction of air velocity values, as well as calibration of the devices, is usually made in free streams from ...
air velocity in heat exchanging pipes is less than 2 m/s,while the continuity for heating is poor when the air velocity in heat exchanging pipes is higher than 2.5 m/s.Therefore the rational air velocity in heat exchanging pipes is 2.0 m/s for heating at night when the temperature ...
Alireza Bahadori PhD, in Essentials of Oil and Gas Utilities, 2016 2.8 Inlet and discharge piping 2.8.1 Air inlet The air inlet should always be located far enough from steam, gas, or oil engine exhaust pipes to ensure that the air will be free from dust, dirt, moisture, and contaminatio...
In order to assess the viability of hydraulically removing air that accumulates in pipes, an experimental investigation was undertaken of the movement of air pockets in a pipeline with different slopes, from horizontal to around 22°. From the test results a prediction equation was developed for ...
C1 = conveying-line inlet air velocity, m/s T1 = conveying-line inlet air temperature, K Equation 24.1 can be used to check the specification of an air mover, given the conveying-line inlet air velocity and other parameters. Rearranging Eqn. 24.1 in terms of conveying-line inlet air veloci...

In this study, all internal structures of the pig house were designed similarly except for thin pipes and wires that did not significantly affect the airflow, and the actual shape of the pigs were designed to be the size of a 7-week-old piglet. In addition, the ventilation structure was ...
The buoyant force tends to move air pockets upward while drag tugs air in the direction of the flow. Since these forces act in the same direction in upward-sloping segments, air here naturally moves downstream. By contrast, in horizontal or descending pipes, a minimum water velocity must be ...
