Tender capacity

[oldline1]

I'm converting several steam loco tenders and this is causing the tender and water capacities to change from the as-built specs.

OK..............here's the question.........how much cubic capacity does a ton of bituminous coal take up? What about the water? How to properly figure the new tender capacities?

Thanks,

Roger

Well, here's your chance to break out the slide rule or calculator: broken bituminous coal has a density of 833Kg/Cubic Meter.

And, since we're going metric, one cubic meter of water masses one metric ton (2200 lb.)

And to further confuse you:

• 833Kg of bituminous coal = 1832.6 pounds
• 2000 lbs. of bituminous coal = 909.1 Kg
• 1 Cubic Meter = 1.30795 Cubic Yards
• 1 Cubic Meter = 35.3146 Cubic Feet

I remember seeing something that stated a ton of coal is about the same size as a refrigerator.

So there is a basic idea of the volume of a ton of coal.

Actually, a cubic metre of water (distilled water at 15 degrees C) has a mass of 1000 kilograms, or one tonne.

So what's the power output of a Big Boy, in furlong grains per fortnight so we don't have to do all those silly metric conversions?

I recently received a Spectrum Russian Decapod 2-10-0 in Western Maryland markings, with  tender capacity indicated as "20,000" on the upper left hand rear end - liters maybe but not gallons for sure in that small tender.  Out of curiosity, taking one of my 2-8-0's which had an indicated tender capacity of 5000 gallons I measured the water tank dimensions in inches, calculated the cubic inches, then cubic ft, then scaled up by 87, then converted to U.S. gallons, and surprise surprise I got near 5000 gallons. Took me almost half an hour, given all those fractions and calculations! 

I have to do the same for my unmarked Russians but if someone already has a valid capacity for the small Russian tender I be happy to know it, the same for my unmarked Spectrum 2-10-2 and Spectrum 2-6-6-2 tenders. 

 PS: Fortunately I had to return the Western Maryland Decapod to Bachmann due a problem and received an undecorated one in return, saving me from the work involved in re-lettering to Grizzly Northern markings.

A gallon of water is equal to 231 cubic inches......you can easily calculate the water tank capacity by multiplying length x width x height in inches, then divide by 231 to determine the gallonage of the water tank.

612,350 Newtons. For a drawbar horsepower of 4,623 kilowatts. Sustained for 1 hour, that would be 16,644,024,000 Joules.

The machine had a mass of 548,280 kilos gross. Or 548.28 tonnes.

You can do the math in those old units.

According to my Western Maryland specs their I-1 Russian tenders held 7,400 gallons and 17 tons as compared to the "standard" Russian tender's 9 tons.

Wouldn't happen to have a spare WM Dec tender, would you?
