Question

If an aircraft’s fuel has a relative density (specific gravity) of 0.78, what would 1,000 litres of fuel weigh in lbs? (assume 1 kg = 2.202 lbs).
Just checking if my answer is correct. I got 1717.5 lbs

Answer 1

Also "At time 1050 you see another aircraft on a bearing of 040° at a range of
10 miles. If at 1056 the bearing remains 040° but the range has reduced
to 8 miles. At what time will the range reduce to 1 mile, assuming the
bearing remains constant?"

Got 1117 hrs.
these are just questions I am unsure of

Answer 2

what does the .78 represent? lbs, kgs, or what?

Answer 3

I am guessing the density. I know that density is mass/volume but wasnt quite sure if the litres is a volumn of something

Answer 4

literes is volume; if we know that .76 is a specific weight, but how is that weight measured... in kgs, lbs, etc....

Answer 5

i would assume kgs...

Answer 6

780 kgs = how many lbs? is the question I get from this...

Answer 7

780(2.202) = weight in lbs...

1717.56 lbs of fuel for 1000 liters

Answer 8

.78 grams/liter
.78 kg/liter

.78 is rather vague, but whats the definition for specific gravity?

Answer 9

Oh so i basically got it it right but I slightly misunderstood the question. Well I actually didnt remember what specific gravity but I just assumed the 0.78 was the density cos of it said the relative density

Answer 10

what specific gravity is*

Ok, the litres therefore becames the volume as a result cos its just a relative density.
Ok thanks what about my second question

Answer 11

theres a second question?

Answer 12

yeah in the comments, could I make a new post?

Answer 13

should*

Answer 14

new post it just for clarities sake :)
