How much do balloon sizes and flying times vary?
Note: Balloon quality may vary as much as 20% depending on how tightly the balloon clusters are packed. Note: The listed average inflation sizes and flying times are conservative averages. Actual flying times vary depending on temperature and atmospheric conditions.
How much helium do you need to launch a balloon?
You divide the weight of your balloon and payload (2400 g) by 28 g/cu.ft. to get the total number of cubic feet of helium required for your launch (2400 g ÷ 28 g/cu.ft = 86 cu.ft.). You inflate your balloon with 86 cu.ft. of helium and release your payload.
How much does a weather balloon weigh?
Balloon sizes are measured by their weight in grams. A 350 g weather balloon weighs ~ 350 grams. A 1200 g weather balloon weighs ~ 1200 grams. The larger the balloon size (the more it weighs), the larger its diameter/volume will be before it bursts.
How do you inflate a balloon for a party?
Inflate your balloons as close to the event as possible. Balloons look best when they're fresh. Confetti balloons will start to look cloudy overnight. This chart is based on filling your balloons with pure helium. Many helium tanks are diluted with air which shortens float time.

How many cubic feet does a balloon hold?
If instead you used small spherical (one foot diameter) balloons (which holds about 0.526 cubic feet of gas), it would take over 2754 of them to lift the 100 pounds. Therefore a handful of small balloons will not lift you off the ground.
How many balloons will 8.9 cubic feet helium fill?
30 9Small pre-filled tanks hold about 8.9 cu ft of helium. They fill about 30 9″ latex balloons. So that's around 3.3 balloons per cubic foot of helium.

How many balloons does it take to lift a cat?
Understand, 500 balloons will get you the bare minimum. If you want to lift your cat higher or more quickly, then you will need to add more balloons to the bunch.
How many balloons will 14.9 cubic feet of helium fill?
Highlights. Jumbo tank inflates up to (50) 9" latex balloons, (27) 12" latex balloons or (27) 18" foil balloons.

How many balloons can a 20 cu ft helium tank fill?
Our 20 cu ft Helium Tank will fill about 40 standard size balloons inflated to 11". Our 30 cu ft Helium Tank Rental will fill about 60 standard sized 11" balloons.
Does a balloon have volume?
So, we can confidently say that for the gas inside the balloon, the volume of the gas, and therefore the volume of the balloon, is directly proportional to the temperature of the gas, which is also the air temperature.
How do you calculate cubic volume?
To find the volume of a box, simply multiply length, width, and height — and you're good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.
How do you calculate cubic area?
Square feet: You can find the area or square footage of a space by multiplying the length and width. Then multiply this figure by the height to find the cubic space, or cubic footage, within the object. 2.
How much does a weather balloon weigh?
Balloon sizes are measured by their weight in grams. A 350 g weather balloon weighs ~ 350 grams. A 1200 g weather balloon weighs ~ 1200 grams. The larger the balloon size (the more it weighs), the larger its diameter/volume will be before it bursts.
Why does a balloon float in front of you?
This is because your balloon has only enough helium to lift its own weight and the weight of the payload. It's at perfect equilibrium. You need a force that will make the balloon and payload rise upward.
What happens if you launch two payloads with the same size balloon?
If you launch two payloads with the same size balloon, the balloon with the least amount of helium will burst at the higher altitude. Step 1 - Input your balloon size, payload weight, and positive lift of 100 g into the calculator.
What is the lift force of helium?
The lift force created by this additional helium is called positive lift. The more helium you add to your balloon in addition to the helium used to lift the weight of the payload and the balloon itself, the more positive lift you will have. The more positive lift you have, the faster your payload will climb.
Does weight of payload include weight of balloon?
The weight of the payload does NOT include the weight of the balloon. Your positive lift in grams - This number will make more sense as you learn how to use our Balloon Performance Calculator. For now just start with an initial guess of 100 grams.
Why do balloons burst?
Helium tanks diluted with air are ideal for confetti balloons, since air helps the confetti stick to the sides. Avoid sharp objects and fluctuations in temperature. Heat causes helium to expand, and is a common culprit of burst balloons.
Can you put balloons in a hot car?
Do not place your balloons near a heat source such as a ceiling light, heater, fireplace, or in a hot car. *Because the filling and usage of display balloons is beyond our control, no performance or longevity guarantee can be made.
Balloon Arch Length Formula
Example 1: If the balloon arch is wider than it is tall: Height + Width = Approximate Total Length Example 2: If the balloon arch height and width are about the same: 1.5 (Height) + Width = Approximate Total Length Example 3: If the balloon arch is taller than it is wide: 2 (Height) + Width = Approximate Total Length

Note: Balloon quality may vary as much as 20% depending on how tightly the balloon clusters are packed.
Helium Balloon Flying Time
Note: The listed average inflation sizes and flying times are conservative averages. Actual flying times vary depending on temperature and atmospheric conditions.
