Converting 29680 litres, to pounds?

Question

How would you convert 29680litres into pounds (as it weight)

Thanks.

Answer 1

Water weighs about 10Lbs per gal.

Avgas = 6Lbs per gal

Jet A1 = 7Lbs per gal

All these convertions are done on US gal

1 USG = 4.546 liters where a IMP Gal = 3.785 liters.

There are alot of things that changes the SG of a liquid. Temp is one of the biggest of all.

Ok so 29680 l = 6528.816 USG = 45701.71 Lbs

This would also only be under ISA conditions

Answer 2

A litre is a measure of volume, while a pound is (among other things) a measure of weight. They are two different things. For example, a litre of Mercury (liquid metal) will weigh way more than a liter of water.

The weight of a specific volume of any substance is called it's 'density' - so Mercury, weighing more per liter than water, is said to be more denser than water.

Coming back to your question, if you are talking about water, it weighs 1 kg per liter, so 29680 liters of water weigh 29.680 kgs, or 65,433 pounds. This is a slightly simplified answer, as density changes with purity, temperature and pressure.

The Airbus A320 and A321 have a fuel tank with a volume capacity of 29680 liters. If you fill this tank with jet fuel (density 0.72 kg/l), it will take 47112 pounds of fuel.

If you fill the same fuel tank with water instead, it will weigh 65,433 pounds. On the other hand, if for some reason you decide to fill it with Mercury, it will weigh 8,89,888 pounds (and the fuel tank will most probably break under it's own weight!).

Answer 3

basing on my Fuel Specific Gravity Conversion table which is taped to my calculator, the one i use whenever I refuel aircrafts 29680liters is = 52533.6lbs. This is for aircraft mechanics  only or when your assigned to an outstation.

Answer 4

It depends on litres of what?  Air?  Water, Jet Fuel?  Ice Cream?

There's about 4-1/2 litres per gallon, and fuel weighs about 6.84 pounds per gallon.  Water weighs about 7-1/2 pounds per gallon.  So you can figure these yourself, right?

Come to think of it, about a cup of Breyer's Heath Bar Crunch would be great right now.  It will weigh more after I eat it than it did before.

EDIT:  Okay, so 29680 divided by 4.5 = 6595 gallons.  Sounds like a Boeing 727 or some kind of regional airliner.

So 6595 times 6.84 pounds per gallon is 45,110 pounds.  There.  You do it next time, okay?

Correction:  After eating some ice cream, I remembered that Jet A weighs 6.84 pounds per gallon, rather than 6.0 as I had written earlier.

Answer 5

The reason why you're getting different answers is because Jet-A density varies.  I've personally measured the specific gravity of fuel at 0.790 to 0.840 kg/l. (1.738 to 1.848 pounds/liter)  So multiply that by 29680 and it could be anywhere between 51,583 and 54,848 pounds, could be even more or less depending on temperature.  

If the flight plan requires 54,000 lbs and you pump in 29680litres of warm fuel with a SG of  0.790, they'll be short more than 2400 lbs.

You'll need a hydrometer to measure the SG to get the right answer.

Answer 6

29680 liters is 7840.6 gallons

Jet-a=A weighs 6.74 lb/gal

so 7840.6 x 6.74 = 52845.6 lbs
