1400 cfm blower 10 inch Spiral

Room is 24×50 I want to discharge air on 3 walls with windows and doors. 10 inch spiral duct. Am I designing a whistle?

Indoor pool room?
What are your design specs for temperature and humidity?
What equipment are you using for conditioning? How much outdoor air?
That’s a lot of air through 10” duct.

DIY project no specs. Floor has radiant tubing. Unit is a 3 ton desert aire dehumidifier with 1400 cfm blower. Aiming to keep it 82ish both air and water, humidity south of mold growth potential. I was thinking I could put long registers in the duct just a inch or 2 high and get the fan of air to force against the glass. 10 inch seems small however the duct with 3 90s just about 90 feet total would have 11 openings with 2 inch opening 36 inches long? I dont know what I dont know appreciate any guidance and advice. The 10 inch is a deal so if I can make it work its nearly free, budget now includes the capturing of rain water and possible snow melt

We can’t really help you design your own pool room.
The air and water temperature need deadband to avoid evaporation.
A pool room isn’t really a project to throw together off the cuff. Seen many a pool room fail miserably due to poor design.

I must say that is an attractive pool & room!

I dont believe evaporation can be avoided, however with close temps of water and air it can be minimized. The biggest concern is condensation on the glass, forget the pool, does 90 foot of 10 inch duct with 11 36”x2” openings whistle like a train? destroy my blower? ruin my unit? I thought i could choke registers in the beginning and adjust each opening to balance the flow. nearly 800 sq inches of opening?

Best worst idea Ive had lately.

You have a real project on your hands that needs professional attention.

Due to the forum rules (no DIY), we will not be able to consult you on this project.

Thanks for your understanding.

We understand the rules, lol@ professional attention at this point we just need water. Question was merely on duct size, I figure there is one correct way, a dozen or so that will work, and endless incorrect methods. I was looking for what will work. Great job as Mod though

I would revisit your duct design specs.

And room design conditions.

And note the bright red banner at the top of the page that clearly indicates no DIY information is available here.

I see that as my answer Rider, 10 is inadequate. Thank you.

That’s not what I intended or suggested but do as you wish.

This isn’t a good learn as you go project.
Recently I did a job at a hotel with a poorly planned pool room. It would up having to be gutted and completely redone do to moisture and mold growth.
OA is a very important consideration as well.
