You must first calculate the flowrate via the equation (or equivalent) mentioned above before calculating the velocity. This is air at a constant temp so the density of the air will vary with pressure. The mass flow is constant at any point in the pipe. The mean velocity at a point in...
You can checkthis list to get an idea of how much CFM the best air purifiers can produce(for reference). It is also interesting to see how theCADR rating for dust-removing air purifiers depends on airflow. You can freely use the CFM calculator to calculate airflow for any room, and fo...
which you can often determine by measuring the cross-sectional area A of the pipe, duct or riverbed. The second quantity is the velocity v of the air or water at that point. You
Duct size is determined by the velocity of airflow needed to supply the part of the building the duct is servicing. Airflow is measured in cubic feet per minute (CFM), but duct dimensions are typically measured in inches, which calls for a conversion factor to convert a cross-sectional are...
Hello Ansys community,I have the geometry STL file and I am going to convert it to solid geometry by SpaceClaim software and get an Export in STEP format from it. First, I Imported the STL file in SpaceClaim, then I selected the Auto-Skin option from the
In a Venturi tube, there are solid walls which constrict the flow, requiring more velocity in order to pass all the mass coming into the section of the duct where the area is lower. This is not true of an airfoil, which is an open flow that can easily deflect around the air...
For the configuration shown below what must be values of the specific weight of the unknown fluid ( answer in units of psf) How to determine the averaged droplet size of the atomizer and the averaged velocity of flying droplets? Provide a formula used to ca...
There is a limit to the temperature difference across the cooling coil that air-cooled equipment can produce because of the refrigeration cycle. These types of units can typically produce a 20°F to 25°F delta T in the cooling condition. An engineer should always calculate the entering air ...
1. Air velocity within the system is measured in feet per minute, or ft/m. 2. The system must be carefully engineered to keep the air speed within an acceptable range to prevent two major issues. 3. Air speed is related to CFM as follows: ft/m = CFM ÷ cross sectional...
The first thing you need to do, is to figure the quantity and velocity of the air in the tunnel. Use the formula Q=AV where Q=the quantity of flow, A is the cross sectional area of the duct and V= the velocity of the airstream. With this information, you can then use a fan man...
