little known Diesel facts... Queen Elizabeth II fuel consumption.

CORRECTION - June 21, 2001

   June 21, 2001:

ANSWER:  26 feet per gallon of fuel  :)
 ...not 6 inche per gallon as I'd read somewhere.  I'll try to recall the source... could
have been Uncle John's Bathroom Reader for all I know. :)

TO GET THE ANSWER:
========================
converting the miles (787.2) to feet, we'd have:

	4,156,416 feet / 159,100.3 gallons  (right???)  (I'm thinking I'm
	doing this right... could be wrong... ;)

26.124501336578246552646349504055  feet per gallon, right?

so, according to these calculations, it should go 26 feet per gallon,
what did my page say?  (looking... 6 inches per gallon??? who
wrote that nonsense?  ;)  Actually I got it from somewhere else, and
I appreciate you questioning it, because I did too... just never had
the info from the page you cited...  :)


787.2 / 159,100.3 gallons = 
0.00494782222283678911981938437576799 miles per gallon

-----------------------------------------------------
Fuel consumption:    18.05 tons per hour (433 tons per day) on 9 diesels
Fuel oil: 4,381.4 tons 
	Assuming a metric ton = 2204.623 lbs
and Diesel oil probably weighs about 6 lbs per gallon

433 tons * 2204.623 = 954601.759 lbs per day / 6 lbs = 159,100.2931667 gallons per day

Service speed - 28.5 knots  at 433 tons per day...
	service speed = 32.79721 mph

(if it weighed 7 lbs it would be = 136,371.67985 per day.)

assuming 32.8 mph * 24 hrs, we'd go 787.2 miles

787.2 / 159,100.3 gallons = 0.00494782222283678911981938437576799 miles per gallon
what is that, 5 thousandths of a mile?   :)
my brain hurts... but these numbers seem close to what the page I put together says, doesn't it?  :)

My son came home from school saying that the QE II travels 6 inches per
gallon of fuel.  I told him that he must be mistaken, so I looked it up on
the web.

I found your page and others that claim this fact.  My calculations (from
http://www.travelonline.co.nz/new-cruises/qe2/shipfacts.html ) indicate otherwise.

To use your facts, if the QE II uses 38,484,336 gallons of fuel per
cross-Atlantic crossing, that would be 21,991 gallons of fuel per passenger
(1750 passengers).  Alternatively, 38,484,336 gallons of fuel oil weighs
about 107,756 tons.  According to the site listed above, the QE II only
carries 4381 tons of fuel oil.

I thought you would want to know.

(thanx Tom! - john)

 this is not correct based on the info found on the link above

  The cruise liner, Queen Elizabeth II, moves only six inches for
              each  gallon of Diesel that it burns.

			6 inches => 1 gallon
			12 inches => 2 gallons
			1 mile = 5,280 feet =>  10,560 gallons

From NY, NY to Southampton, England --> 3,169 nautical miles
	statue miles = nautical * 1.15 =>  3,644.35 statue miles

 3644.35 * 10560 =  38,484,336 gallons used !!!

(see above for a more likely answer)


I wonder what the fuel consumption would be IF they could use gasoline... :)

BTW, the April 99 issue of Automobile Magazine, pg 28, cites that
Diesels are 40% MORE efficient than gas engines and produce 50% LOWER
Carbon Dioxide emissions!   (also, the oxides of Nitrogen are typically
40 to 50% less than a comparable gas engine, see Chilton's DIESEL Guide)

The article discussed future uses of Diesel engines that meet tighter federal 
and California emission standards AND fuel economy.
The key is the fuel itself.  Much of the current Diesel fuel still has
too much sulfur in it to use a catalytic converter.  HOWEVER, using synthesized
Diesel fuel created from wood, as the Germans did in WWII, they can create
a Fuel that is very enviromentally friendly!

BTW, the smell most people dislike about Diesels is the aldehyde.
