Would you travel (drive or fly) longer to fly in a 14ft tunnel vs 12ft?

Thanks Jeremy!

FWIW, AFAIK Perris and Orlando are measured just short of 12 ft corner to corner and are 10 sided.

Airkix, NH and CO are 12 ft flat to flat and are 8 sided.

Thanks for the info - I was relaying what a tunnel rat had mentioned in these forums.

{{I could have sworn the Orlando tunnel was 12 sided.... But, my memory goes as I get older. You sound like you know the details}}

I dont think they can be measured flat-to-flat based on what I have seen in the past. Not wanting to start a shitstorm here so lay off me folks!

To show why I think this see the attached photo - which unless these people are 7ft tall gives a good perspective. This photo is from SVNH which I would guess is 12ft corner to corner (as CO and Airkix)

SVCO has some great employees and the recirculating air is warm and smooth. Does size matter? Not if you know how to fly in place and stay in the wind column. I've seen people with 500 jumps that are all over the place in the tunnel. Granted it's nowhere near Mile High DZ, but the people are great and so is the tunnel. ...but then again I'm only 2 jumps away from being a total whuffo...I'd imagine my opinion hardly counts!

There's three types of people in this world...those who can do math and those who can't!

I just ran upstairs and measured the (SVCO) tunnel. 11-ft, 5-inches from flat to flat and 12-feet, 5-inches corner to corner. We have 8 panels. Maybe the 12 feet is an average. I 'believe' it is 109 sq ft. That might be the best way to measure a tunnel, square footage.

Hey Derek,

Your way is a lot simpler and precise than mine! Thanks for taking the time to do that.

A further step to the idea of using area rather than diameter... is volume! For me this is ultimately the most important metric of any tunnel....

It is volume that dictates your power needs / how much space there is to fly... and how long it takes a fart to dissipate (all very important!)

But - a little of a digression on topic..... ErmM I would travel a little extra to use a 14ft tunnel over a 12ft one but would still probably use both in any event.

Fun with math! See the attached Excel spreadsheet (in zip file) or PDF file if you don't like Excel.

Something to consider is that since the area of a circle math formula is Pi R squared, the area of the 14 foot tunnel is substantially larger due to the radius "squaring". Therefore, a 12 ft. tunnel has 113. 09 sq. ft. of area, where the 14 ft. tunnel has an area of 153.93 sq. ft, no matter how it is measured.

All you did was say that a 14 foot tunnel is bigger than a 12 foot tunnel. I suspect nobody will dispute that at all.

How many hours of tunnel time do you have?

Why do you ask? This thread has digressed to tunnel "area" for circular vs (various ways to measure) polygon tunnels (I thought the actual measurements from some of the owners and employees was very interesting).

I which case, maybe asking how much math I have trained in, or an IQ would be appropriate.

Didn't you know there was a direct correlation between tunnel time and maths ability? Rusty just solved fermats last....

"maths" - I find that funny. SC has a good point, the details don't matter when we are picking at differences of a couple feet across. (Though we use the 'corners' quite a bit, it seems).

Hey Derek,

I just wanted to thank you for all the help you are giving me and my instructor (Brad Cole) in the tunnel over a SVCO. It is amazing now living in a city that has its own tunnel. By the way, Brad is out of town Sunday and YOU are my coach that night!!! This twice a week training is sucking the wind out of my account and blowing it into the tunnel!

Peace,
Oz

I just had some engineers do the numbers for the Colorado tunnel (based off your measurements) and your sq foot calc is pretty good. They came up with 108.0405 sq. feet
