Check air flow rates of quadrangular ducts

For quadrangular ducts or vents, by entering the dimensions of the sides and the air speed either in meters per second or meters per minute, you immediately obtain the air flow rates in different formats (mXNUMX/h - mXNUMX/sec - liters minute). The calculation of the cubic volume of the rooms completes the work.

The verification of the air flows passing through the quadrangular channels is a crucial component in the field of engineering, safety and air quality. The importance of a program dedicated to this verification cannot be underestimated, as it has a significant impact on various aspects of daily life and industry.

First, it is essential to ensure adequate and safe airflow in the ducts for a number of applications. These channels are used in ventilation systems to ensure proper air circulation in buildings, hospitals, industrial plants and other facilities. Failure to accurately verify airflow rates can lead to serious health problems, including air quality risks such as the buildup of pollutants or the spread of noxious particles.

Furthermore, a program of verification of the air flows in the ducts is essential to guarantee the energy efficiency of the ventilation systems. Inadequate or non-optimized airflow can lead to a significant increase in energy consumption, with consequent higher costs and negative impacts on the environment. Accurately verifying airflow rates helps identify and resolve inefficiency issues, thereby improving the sustainability of industrial operations and buildings.

From a safety perspective, an airflow testing program can help prevent contamination incidents. In high-risk industries, such as the chemical industry or waste management, proper airflow in ducts can be critical for the rapid dilution of hazardous substances and for the protection of workers and the surrounding environment.

Air quality

Finally, indoor air quality is a critical factor for people's health and well-being. An airflow testing program helps ensure that the air breathed in buildings is clean, fresh and free of contaminants, thereby improving the quality of life and productivity of the people who work or reside there.

In summary, a program dedicated to verifying airflows in ducts is essential to ensure safety, energy efficiency, sustainability and public health. Investing in tools and technologies for this verification is a crucial step in promoting a safer, healthier and more efficient environment for all.

How to calculate how much air passes through the ducts or exits from quadrangular diffusers.

By inserting the dimensions of the sides and the air speed (in meters second or meters minute), the air flow rates are immediately obtained in different formats (m³ / h - m³ / sec - liters minute).

The calculation of the cubature of the rooms completes the paper.

Check air flow rates of quadrangular ducts

How many times has it happened to you to calculate how many cubic meters of air pass through a duct or through a diffuser?

This simple program will make your work easier.

How to proceed

1 - the first thing that needs to be done is the choice in the drop-down menu of what we are going to analyze: RECTANGULAR CHANNELS or NOZZLES - GRIDS (if you want you can fill in the project data)

2 - we set with which measure we will indicate the air speed (meters per second or meters per minute)

3 - we name the trunks (or diffusers)

4 - let's enter the dimensions of the ducts or diffusers

5 - done.

Let's take an example for channeling with an anemometer set in meters per second

Let's read the results:

all the logs taken into consideration have a total flow rate of 4.770 m³ / h

Let's take an example for the speakers by setting the anemometer in meters per minute

In this case we will also enter the dimensions of the rooms served by the diffusers, obtaining the cubes and how many air recirculations will affect the rooms.

Easier than that

good job
