Task:
Calculate the airflow velocity if the inner diameter of the pipe is 50 mm and the flow rate is 100 m3/h at a pressure of 3 bar and a temperature of 15 C


Let's calculate the speed of airflow in a closed pipe.
Select the pipe diameter calculator on the left.
After that, select the fluids tab, then click on the gas button and select air from the list.
We see on the right that volume flow is selected as a quantity that needs to be provided.
Let's choose to enter temperature instead of density.
In that case, we also need to enter the fluid pressure in the pipe.
Enter 3 bars in the text field for absolute pressure, as well as 15 degrees Celsius for temperature.
Then we enter the known volume flow of 100 cubic meters per hour.
Since we calculate the flow velocity, we choose from the list on the right to enter the value of the pipe diameter [sPause sec=3 ePause] and enter the value of 50 mm.
Now all the data is entered into the calculator and we can press the calculate button.
We can see that the calculated velocity of airflow in the pipe is 14.147 meters per second.
We can see all the calculated data in the report tab.



Solution: Flow velocity is 14.15 m/s
