Hi,
I've been using Hevacomp Netsys to calculate the ventilation system resistance. However, the results seem a bit high and I don't know why. The entire system is only within one large room and the results show 119 Pa. Velocities do not exceed 3 m/s.
Would you be able to look at that, please?
Thank you,
Pat
Hi Patrycja,
Thanks for raising this issue! Can you share your Netsys project (zipped) with us through the link below so we can dive into the same?

Hi Krishnendu,
I believe I uploaded the file but please let me know if you haven't received this.
Thank you.
Just to let you know Krishnendu has shared your project with me and I am looking into this now for you. I will be in touch shortly.

Brilliant, thank you.
So the high pressure is predominantly due to section 1:
Specifically, the three fittings along section 1 that have been added account for the extra pressure - see results with these removed:
I hope this is of assistance.
Hi Shane, I see, thank you for your help, much appreciated.
