Where exactly is there a flow of 49 m³/h (29 cfm) in a pipe?
The calculation is by Helios.

As with any trade, you should approach things with common sense and understanding. A deviation of 3.3 percent is acceptable. Or do you notice any difference in your house between an air exchange rate of 0.34 and 0.35?

Hello

From posts 46, 47, and 48, it can be understood that only one pipe is planned per room. I’m sure I am not the only one who interpreted it this way.
With installation and proper balancing of the valves according to the above, using the corresponding number of pipes, which I initially also overlooked, everything should then work correctly.

And before anyone notices,
... according to the plans, the rooms have either supply or exhaust ventilation only. So, now I have complained a bit in one of your threads.

Yes, that is clear.

However, I did not understand the part about the ventilation.
