A pilot requests 9.2 tonnes of fuel. The bowser driver reports to the pilot that the specific gravity is 0.8, what will the uplift be?
- 10200 litres.
- 11500 litres.
- 14375 litres.
Explanation
Volume equals mass divided by density. With specific gravity 0.8, the fuel density is 800 kg/m3, so 9.2 tonnes (9200 kg) occupies 9200 / 800 = 11.5 m3, which is 11500 litres. Treating the fuel as if it had the density of water would wrongly give a smaller figure.

Can someone explain this ?

9200/0.8=11500

If specific gravity of fuel is 0.8 and weight of fuel is 9200kg, volume of this quantity of fuel will be bigger than 7360litres or 9200litres. So it is 11500... Or just divide it without calculator, if it easiest way for you.
