[Steam-engine] heating surface

[Dan Donaldson]

Travis,

Try this

[O.D. - (2 x wall thickness)] x pi x length / 144 = square feet

[2 - (2 x .125?)] x pi x 45 / 144 = 1.718 square feet per tube

This is how I would do it anyway.  Someone else may have a better way.

Subject: [Steam-engine] heating surface

I most likely should have payed closer attention in math class, but no one
ever taught it as it applies to steam engines.  (what a great idea!)  anyhow
does anyone care to educate me on the heating surface of a tube?  It is 2"
in diameter and 45 inches long.  I keep getting interesting answers.... but
am not sure they are right.
   
  thanks
