So to lift a 40 pound child 182 kg it would take 18201 1820 balloons. A normal balloon at an amusement park might be 30 centimeters about 1 foot in diameter.
How Many Balloons Does It Take To Launch Your Kid Wired
It took 53 12 helium balloons to lift a pound you have to addthe weight of the string and balloons.
. If instead you used small spherical one foot diameter balloons which holds about 0526 cubic feet of gas it. How much helium would be required to lift a mass of 35 lb. This ultimately will need to be adjusted for the weight of the balloons and the string.
To solve this determine the amount of buoyant lift force for a typical helium balloon and then divide 40 pounds by this force to get the number of balloons needed. To determine how many liters of helium a sphere can hold the equation is. The volume of an ideal gas is 2241 Lmol at STP.
To lift the weight youd need more than 407 1-Liter balloons. 26 rows Balloon Lift Ability Gas Capacity Average per 242 Cu. As a result lifting 5 pounds about 2268 grams would require over 162 balloons.
A pound is 453 grams so it would take 183 moles of helium to lift each pound. A typical amusement park helium balloon might have a lifting capacity of 10 grams 001 kg. A normal helium balloon can lift approximately 14 grams.
Divide by 448 the number of grams. One cubic foot of helium will lift about 282 grams so multiply the volume of the balloon by 282. Roughly 1 cubic metre will lift about 1 Kg.
Therefore each cubic foot of helium could lift 0069 pounds. According to How Helium Balloons Work the lifting force of 1 litre of Helium is about 1 gram. Thats a lot of.
If you hook 407 1-Liter helium balloons to the 1-pound object it would neither sink nor float. Note however that this is an estimate and may vary. In order to lift 100 pounds which would include the weight of your load the balloon and the helium you would need 1449 cubic feet of helium.
454 gramspound x 0896 Litersgram 407 Literspound. Tank Average Float Time Float. Reply 10 on.
This would require a balloon with about a 155 foot diameter. Most houses weigh between 80000 and 160000 pounds Given that 1 cubic foot of helium can lift 0067 pounds it would take 1492537 cubic feet of helium to lift the houseor about as much as would be contained in 105854 balloons each 3 feet in diameter.
