Air ducting speed section flow rate

Air ducting speed section capacity

Flow rate section speed circular air ducts

Simple program that calculates the relationship between section flow rate and speed in the air ducts (avoids the use of the table: “Air channels – flow rate, size, speed” which remains limited in the air flow rates) – Simply enter any two values and the program calculates the third – Calculations can be performed in the International System (SI) and in the British Imperial System (Anglo-Saxon System).

This program, designed and created by Itieffe, is a very useful tool for engineers, designers and operators working in the field of air, air conditioning and ventilation engineering. This tool provides the ability to calculate air flow, cross-section and velocity within ducts, ducts or ventilation systems in both international and non-UK systems. Before examining the specific content of the program, it is important to provide a background to understand the context and importance of this resource.

Context of air (aeraulic) and air conditioning engineering:

Air and climate engineering is a crucial discipline in construction, industry and the environment. Efficient air management is essential to ensure thermal comfort, indoor air quality and the optimal functioning of ventilation and air conditioning devices.

Air flow, section and speed:

The air flow rate, section and speed are key parameters in the design and management of ventilation and air conditioning systems. These parameters directly influence the distribution of air, the dispersion of pollutants and particles, as well as the energy efficiency of the systems.

Importance of this Program:

This program is of significant importance for several reasons:

Optimized design: allows you to design ventilation and air conditioning systems efficiently, correctly sizing the ducts and optimizing air distribution.
Performance monitoring: Enables constant monitoring of systems performance, detecting any deviations from design specifications.
Energy efficiency: helps to improve energy efficiency, avoiding energy waste due to non-optimal speeds and flow rates.
Air quality control: Helps maintain high indoor air quality standards, which are essential for the health and comfort of building occupants.

Conclusion

In conclusion, the program that itieffe makes available free of charge represents a very useful tool for guaranteeing a quick calculation of air flow, air speed and sections. Its adoption facilitates the design, monitoring and optimal management of these systems, contributing to the comfort, health and energy efficiency of the environments in which they are installed.

Air ducting speed section capacity

Program that calculates the relationship between section flow rate and speed in the air ducts (avoids the use of the table: "Air channels - flow rate, size, speed" which remains limited in the air flow rates

Just enter any two values and the program calculates the third.

Calculations can be made in the international system and in the British Imperial system (Anglo-Saxon system)

Instructions

International system

Let's consider a machine that treats 12.000 m³/ h of air that has a speed of 5 m / s.

By entering the TWO data, you will immediately find the diameter necessary for the circular ducting calculated which will be equal to 922 mm.

The front section of the circular duct will also be indicated, in this case, m² 0,67.

If we want to calculate the dimensions of the duct if it were quadrangular, just enter the length of side 1 and see the result.

In this case we have indicated side 1 equal to 900 mm and we have had as a result of side 2, 750 mm.

Obviously you can search for other results with different interpolation, for example with the diameter and air speed, you will find the air flow and with the air flow and diameter you will find the air speed.

Flow rate section speed circular air ducts

Anglo-Saxon system

Consider a machine that treats 5.900 cubic foot minute (985 CFM) of air that has a speed of XNUMX fpm (foot per minute).

By entering the TWO data, you will immediately find the diameter necessary for the circular ducting calculated which will be equal to 33 in (inches).

The front section of the circular duct will also be indicated, in this case, ft² 5,97 (square feet).

If we want to calculate the dimensions of the duct if it were quadrangular, just enter the length of side 1 and see the result.

In this case we have indicated side 1 equal to in 33 and we have had as a result of side 2, in 28.

The same rules apply to search for other results with different interpolation, for example with the diameter and the air speed, the air flow will be found and with the air flow and diameter the air speed will be found.
