Re: Odd K-37 question.

Warning: engineering geeking out for a bit.

So I pulled up the WP&Y spec sheet posted earlier on a different thread. Violet is 66", with 182 tubes, 2-1/2 OD. So the area is about 5 ft^2 for the tubes out of 24 ft^2 total boiler cross-sectional area. And if the boiler level is about 75%, that'd mean the water cross-sectional area is 18 ft^2, or about 25-30% of the watery area. That means the boiler would normally have about 1/2 of its cross-sectional area full of water.

And further assuming that boilers tend to be about the same relative dimensions, a74" boiler by 25 long would normally hold about 23,000 lbs of water.

But wait, there's more!

The WPY engine had tubes that are 16'-6" long, so maybe the K-37's boiler was only 20' long instead of 25'. In that case, the water weight would only be about 18-19,000 lbs.

Any body have a spec sheet for the K-37's boiler?
