Area of a disk 3 inches in diameter : 7.068583 square inches. Times 6 billion : 42,411,498,000sqin. The diameter of an exhaust pipe with such an area is 3.6676 miles. Impressive mental image
It becomes a circle packing problem if you want to visualize 6 billion actual exhaust pipes existing next to each other, and the total area of that one would be about equal to the 3.6676 miles times the inverse of circle packing efficiency (1/0.9069 or 1.102657), so about 4.0441 miles in diameter.

A billion 3-inch circular tailpipes have the area of a 1.5 mile tailpipe.
Which would be... Very big.

There's probably like 5 or 6 billion tailpipes
Imagine that pipe 5x as big spewing exhaust 24/7

Area increases quadratically with diameter :

What is a tailpipe
bizzle@lemmy.world · 6 pts · 116d
I believe the Europeans call it a "carse-hole" it's this part

But ICEs are literally trains. They font have tailpipes...?

I think they meant ICE as in "internal combustion engine"

Um, whoosh?

Still smaller than your mom's tailpipe. 😌

It would take 250,826,400 cars with a 2" tailpipe to fit around the earth.
