ok, i suck at math, i'll admit it.

here's my question: i'm trying to get the diameter of a tube. i took a string and wrapped around the tube, and the string's length is 2.25 inches (2 and a quarter). what's the diamater of the tube?

i suck at math...

 

Diameter is the width across the mouth of the tube. Measuring the way you did gets circumference. Radius is the distance from the center of the tube to the edge.

Man, gotta love this site! you can get the answer to any question here...

 

I'm getting your diameter to be .717 inches

I used 2 Pi R= Circum

 

Yeah, but I can't help but feel that the content is on the decline...

Better to use Diam = Circum / Pi. It's the same formula, but yours requires mingster to multiply the radius by 2, and he sucks at math.

(Sorry mingster! )

(I knew that Master's degree in math would be useful one day!)

 

Not to confuse the issue or anything but mingster are you looking for an ID (inside diameter) or an OD (outside diameter)?
These numbers will not be the same based upon the wall thickness of the tube. The difference in ID and OD become extremely important when fitting plumbing pieces together.

 

Oh my, Triple-H is making things all together too complex for poor Mingster's brain.

Ouch....That Hoits!!!
