• ### Helium Balloons Calculator

How many balloons to lift a person. Let's get on with the calculations! As you already learned in the previous section, the lifting force of helium is approximately one gram per liter. It doesn't seem like much, that's why you will need a lot of balloons to start flying! Determine your weight - for instance, 75 kg.

• ### Preparing to Lift an HAB Payload - W1HLO

May 16, 2019· As W1HLO prepares to launch its high altitude balloon (HAB), we need to determine if the weather balloon can lift our payload and how much helium is needed. We have a few 300 gram balloons in stock, so we will be using one of those. The "300 grams" refers to the weight of the balloon when deflated. HABs have a burst altitude – generally, the heavier the balloon the higher the burst …

• ### How much can a 10ft/6ft diameter weather balloon carry ...

May 27, 2010· The lift of the gas in the balloon is measured so that it rises at a constant rate of about 300m a minute with whatever payload it is carrying. If you increase the amount of gas in the balloon, you will get more lift but the balloon will not fly so high. Hydrogen is the gas used in weather balloons as it is lighter and much cheaper than helium.

• ### Weather Balloon Instrument/Radiosonde Information

If the NWS radiosonde comes with a postage paid mailbag (as noted in the instructions printed on the instrument) it can be sent back to the NWS where it may be refurbished and flown again, lowering the cost of the weather balloon program. Follow these instructions for mailing the radiosonde to the NWS:

• ### Can A Few Gas-Filled Balloons Really Lift You Off The ...

The lifting force of a helium-filled balloon is 1 gram per liter. This means that if you fill a balloon with 10 liters of helium gas, it should be able to lift an object no heavier than 10 grams. This is the capacity of a helium-filled balloon when it comes to lifting weights.

• ### Questions About Weather Balloons | StratoStar Project ...
