How much hydrogen is enough to lift up 1 kg weight from the ground?
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 many kg can one bar pressure lift?
This is a kind of trick question. In a closed static system containing fluid, pressure is equal everywhere. This is called the Law of Pascal. One can use this principle to lift a car with a finger. Fill a tank with water and have a car float on a platform. Now make a hole in the tank and connect a tube to it. By preventing the tube to leak, you have to apply a certain pressure, which may be smaller than 1 bar. If you increase the pressure, either by hand or possibly by blowing the tube, you can lift the car. Not so much with a short tube, but more with a long tube. The higher pressure in the tube will push the water back in the tank and cause the water in the tank to rise with the car on top of it.
How much does a cubic decimeter of water weight?
At 4 deg C and a pressure of 1 atmosphere, the mass is 0.999972 kilograms. At this temperature, water is at its most dense. At room temperature (20 deg C) the mass is 0.9982071 kg. The weight will, of course, depend on where on earth (or elsewhere) the weight is measured.
How much does 60 cc of water weight?
Sixty cubic centimeters (cc) of water weighs 60 grams. This is because the density of water is approximately 1 gram per cubic centimeter at standard temperature and pressure. Therefore, the weight in grams is numerically equal to the volume in cc.
How much pressure is required to lift one ton?
Assuming you need a metric ton, that's 1000 kilograms. To lift that, you need a FORCE of 9800 newtons. Force is related to pressure by: pressure = force / area, so the answer to the original question would depend, over what area the force is applied.
