Length and height at a 45 degree angle

I'm working on an airline drawing, need some quick help, please.

If you take a 24' x 24' garage, and run an airline up the wall at 45 degrees and then down again at 45 degrees.

How long would it extend out before it hit the floor and ceiling.

Now we'll assume the garage is longer and has 8 and 9 and 10 and 11 and 12 and 13 and 14 foot high ceilings.

Plus how long is the total length of the pipe in each case.

thanks in advance.

Rob

all numbers rounded to the nearest 0.1
I was getting ready to say the same thing.

At 45 degree angle, the height of the ceiling with be the same as the horizontal run... since going up and back down, the horizontal run will be roughly twice the wall height...
extend out:
~16 feet long for 8 foot ceilings
~18 feet long for 9 foot ceilings
~20 feet long for 10 foot ceilings
~24 feet long for 12foot ceilings
etc
Actually be a little shorter, to account for the diameter of the pipe, etc...

Length of pipe (again, using the 45 degree angle requested) So I used
Length = 2 X (sqrt(wh^2 + wh^2)),
wh= wall height:
~22.6 ft for 8 foot ceilings.
~28.3 ft for 10 foot ceilings.
~34 ft for 12 foot ceilings.
etc

Re: Length and height at a 45 degree angle

Is there anyway to get a sketch of this, then I could copy it and add it to the drawing, then put it on my web site?

Also, do they make 3/4'' pipe in different angles so I could get a little more length, I wouldn't have as much down slope but I want to try and get close to 50' at possible for cooling.

I know I can't get 50' but the pipe has the return run.

Also if a guy went around an inside or outside corner, he could get the length?

Re: Length and height at a 45 degree angle

So let me make sure I understand this, you have an 8' x 12' wall, and the air line is going from the corner up at a 45 degree angle to the ceiling?

I'm out of trig for a long time now but this seems like basic pythagorean theorem to me. You have to right triangles to figure out. Andy69 posted the formula, it is a squared plus b squared = c squared, where c is your "hypotenuse", or in your case, your air line.

|/\| is this about right? Well you have 2 right triangles to figure out the length of the hypotenuse to. Each has a base of 12 feet and a height of 8 feet. 8 squared plus 12 squared is 208. The square root of 208 is 14.422, so with an 8 foot ceiling you would need 28.844 feet of pipe.

With 9 feet ceilings you need 30 feet total. I see I agree with andy's calculations.

Re: Length and height at a 45 degree angle

Heres the finished product, I'll have to figure out some way to add the lenghts you kind gentlemen gave me, but I'll post it like this for now on the body forums, thanks again men.

Re: Length and height at a 45 degree angle

To keep the angle at 45 degrees, the length and height have to be equal.
A sq + B sq = C sq

A= Ht
B= Lt
C= Pipe

8' Ceiling is 8 sqared + 8 sqared = 11' - 3 3/4"
9' = 12' -8 3/4"
10' = 14' -1 11/16"
11' = 15' -6 11/16"
12' = 16' -11 5/8"
13' = 17' -8 5/16"
14' = 19' -9 9/16"


With those ceiling hts the pipe would be tight to the floor and the ceiling at 45 deg. Those would be maximun lenths if you kept the angle 45 deg. Each pipe length would be one side of the 45 deg angle.

So total wall space for each ceiling ht. would be twice the wall ht.
For 8' ceiling, wall space would be 16'
For 9' it would be 18' and so on.

Hope that makes sence.

Re: Length and height at a 45 degree angle

If you take a 24' x 24' garage, and run an airline up the wall at 45 degrees and then down again at 45 degrees.

The only way it will go 45 up to the center and 45 down is if the wall is 24' high. All shorter cases will require a horizontal length of pipe in the center if the angle is 45.

If you want the pipe to angle towards the upper center of the wall then down, it won't be a 45 angle.
