Fluid mechanics? Really.
4600kg=weightdisplacedair-weighthelium
- densityair*volume -densityHe*volume
= V(28.9-4)E3 and V will be in kilo molar volumes (22.4kliters).
solve for V. If you want it in m^3, divide it by a 1000, multiply it by 22.4
HELP!
a 650kg weather balloon is designed to lift a 4600kg package. what volume should the balloon have after being inflated with helium at 0°C and 1atm pressure to lift the total load? (hint. use the density value of helium)
thanks!!
