Airflow Definition and 112 Threads

Airflow, or air flow, is the movement of air. The primary cause of airflow is the existence of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.In engineering, Airflow or air flow is a measurement of the amount of air per unit of time that flows through a particular device.
The flow of air can be induced through mechanical means (such as by operating an electric or manual fan) or can take place passively, as a function of pressure differentials present in the environment.

    Thermo -- Airflow Analysis for Heating Ducts in an HVAC system

    2-48) The 60-W fan of a central heating system is to circulate air through the ducts. The analysis of the flow shows that the fan needs to raise the pressure of air by 50Pa to maintain flow. The fan is located in a horizontal flow section where the diameter is 30cm at both inlet and outlet...

    How Does Box Design Affect Airflow and Velocity Through Multiple Outlets?

    Volume v's Mass airflow...? Can anybody possible help me to understand how the following situation is affected with respect to the Volume and the Mass Airflow/velocity? imagine a sealed square box. On the left hand side is a round inlet. at the bottom are 4 smaller outlets, in a roow from...

    Maximizing Airflow in a Computer: Finding the Optimal Number of Fans

    First off, I'm sorry if there is a more appropriate section for this. There is no section exclusively for fluid physics, and I am not really trying to engineer a prodct, so I posted this here. SO if you have to move it, go easy on me :smile: . Think of a compute as essentially a box with...

    Airflow trough the pipe produces sound

    Good day, gentlemen! A friend of mine asked me a question - he is making a project regarding the influence of the cavity shape on the spectrum of acoustic waves produced after "blowing" into this pipe. You know, many national instruments are based on a principle of the usual pipe. Actually...

    Could Wind Damage My Banner and Sign?

    Outside, I have a south-facing 3'x8' banner that is hung on a fixed sign connected to an L-shaped building. The wall that the banner is on is the inner vertical wall of the L-shape. It is approximately 12-15 inches away from the wall. The sign is a big metal sign (approx 4'x20') with lights...

    Scientific reasons why airfoils are used to straighten airflow

    can anyone tell me the scientific reasons why airfoils are used to straighten airflow (e.g. turbulent flow from a fan or propeller). i know how they are used to produce lift, but cannot see how they straighten airflow. thanx! o:)

    How Fast Can Air Travel Through a 2.5 Inch Pipe at 14.7 PSI?

    Given: you've got a 2.5 inch diameter pipe ... how much air can flow thru the pipe at stoic pressure (14.7)? slightly harder (I think) ... this pipe is 6 ft long, how long would it take to compress the air inside the pipe to 20.7psi, and what would airflow be?

    Uneven Airflow of a Fan: Explained

    Why is the airflow of a fan (a regular house fan for instance) stronger on one side than it is the other? I think it has something to do with the fact that the airflow is a vortex, but I don't understand how this creates uneven airflow. Thanks

    New Computer Case Design - Airflow Dynamics?

    Building a homemade computer case, designed mainly for silence. General theory is computers generate heat, fighting heat (fans) make noise. Heat moves, up, don't fight it. Case will be designed in a chimney fashion. Using many levels will force the sound to bounce back and forth (off of...

    Maximizing Airflow for Screen Printing Table

    hi all, I'm going to be building a screen printing table and ran into a question of airflow. Not being much of a science minded person I came across this site and thought I might find some help. Basically think of a box (4x25x35 roughly) it's airtight. except for a bunch of 1/16" holes drilled...

    Mathematically model airflow over an aerofoil

    Hi! I'm looking for someone who could explain how I can mathematically model airflow over an aerofoil using the "correct theory of lift" - Turning airflow. I have tried several approaches but all fail because of one step... all textbooks I have read on the subject say that the airflow...
