The weight of standard air is 1.2256 Kg/ Cubic Meter
The weight of hydrogen is 0.0857 Kg/ Cubic Meter
The weight of helium is 0.1691 Kg/ Cubic Meter
Subtracting the weight of hydrogen from air gives you the gross buoyant lift of hydrogen as 1.1399 Kg/Cubic Meter
Subtracting the weight of helium from air gives you the gross buoyant lift of helium as 1.0565 Kg/Cubic Meter
These values are variable under altitude, pressure, temperature, humidity and purity of gas.
Hope this helps you.

How much weight kg can you lift with 1 psi of water pressure?
You can lift a locomotive or a house with 1 psi, if the pressure is applied over a large enough area.
What happens when weight is greater than lift?
When weight exceeds lift, an object will descend or fall due to the force of gravity overpowering the upward force created by lift. This typically occurs in aircraft during a stall or when they are unable to generate sufficient lift to maintain altitude. The imbalance between these two forces leads to a decrease in altitude until the forces are equalized or the object reaches the ground.
How maths is used in the wings of the airplanes?
The wings' primary job is to create lift. Lift is needed to overcome the weight of the airplane to allow it to get off the ground and climb. Maths is used in designing a wing which is best shaped to do this whilst also being strong enough to bear the forces it will be subjected to, be large enough to carry the required amount of fuel in its tanks and be streamlined to reduce drag. This is all physics and physics relies on maths to calculate exactly how its laws will be obeyed.
What effort is required to lift a 300 kg weight?
On earth, any vertical force greater than 661.39 pounds will lift a mass of 300 kg.
Why is it easier to circle your wrist than to lift one leg up and draw a circle in the air?
It is easier because the legs carry the whole weight of the body and if you lift it for a longer time your balance will go.
What are different ways to get off the ground and fly?
Have enough lift the overcome weight and enough thrust to overcome drag and you will!
Can Balloons Really Lift A Person Off The Ground?
No, balloons cannot lift a person off the ground. The amount of lift produced by balloons is not enough to support the weight of a person. Additionally, the laws of physics would make it impractical for balloons to overcome the force of gravity acting on a person.
What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How much lift does it take for an airplane to get off the ground?
In order to lift off the ground, the lift force (the upward force generated by the wings) has to be at least as great as the weight of the aircraft. Lift and weight are opposing forces and are equal in straight and level flight.
What was the total weight of the Hindenburg?
I work it out to be 130.1 tones. I worked this out thus:- Hindenburg carried a gas volume of 7,062,000 cubic feet of Hydrogen. This volume of hydrogen, would produce 242.2 tons of gross lift and as Hindenburg's useful lift (the lift left after you subtract the weight of the structure from the gross lift) is documented at 112.1 tons. Thus 242.2-112.1 = 130.1 tones (the weight of the craft).
Is fridge compressor good enough to lift 40kg weight using pneumatic cylinder?
a compressor cant lift..
Dose lift have to be greater than weight for a plane to land?
Yes, in order for a plane to land safely, the lift (created by the wings) must be greater than the weight of the aircraft. This helps the plane maintain control during the descent and landing process.
Can you lift yourself off the ground with a fart?
No, it is physically impossible to lift yourself off the ground with a fart as the force generated is not strong enough to overcome Earth's gravity.
What is free lift in pilot balloon?
The free lift of the Pilot Balloon is defined as the difference between the total lift and the weight of the balloon and its load. The free lift is really the net buoyancy of the balloon. Thus free lift is the force tending to drive the balloon (Hydrogen filled) upward, which depends upon the amount of hydrogen gas filled in it. If a hydrogen balloon is inflated until it floats with certain weight attached to it, than it indicates that the attached weight balances the upward force acting on it. This weight is called free lift of the balloon and if weight is removed, the balloon rises up (with fixed rate of ascent corresponding to weight attached while inflating).
What weight did Neil Hurst lift?
Neil Hurst could list approximately 400 pounds. However, he was trained and fit enough to attempt to lift that much weight.
How much hydrogen gas required to lift 1kg weight?
I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.
How effects ground conditions can have on a lift truck?
Stability, road holding, weight distribution can be compromised
