How much hot air is needed to lift 1 lb?
It takes about 1 cubic foot of hot air at 212°F (100°C) to lift 1 lb. of weight. The temperature of the hot air matters because hot air is less dense than cold air, making it more buoyant.
How much force is used to lift 100 lbs with 2 pulleys?
If you have 2 pulleys in a system to lift a 100 lb object, the amount of force required to lift it would be 50 lbs. This is because the weight is distributed evenly between the two pulleys, therefore reducing the force needed to lift the load.
How many weather balloons to lift 190 lb person?
It would take roughly 67 weather balloons to lift a 190 lb person. Each weather balloon can lift around 3 lbs of weight, so dividing the person's weight by the lifting capacity of one balloon gives the approximate number needed.
How much force to lift 100 lbs using 2 pulleys?
Using 2 pulleys in a block and tackle system reduces the amount of force needed to lift the weight by half, so it would require 50 lbs of force to lift a 100 lb weight. The mechanical advantage of the system allows the load to be distributed among multiple lines, making it easier to lift heavy objects.
HOW BIG A HELIUM BALLOON WOULDIT TAKE TO LIFT A 175 LBS PERSON?
Let's ignore the mass of the balloon itself and the string/rope/harness/whatever that connects it to the person. We're also going to ignore the compression of the balloon; we can assume it's mylar or something and the helium inside is at normal atmospheric pressure (if the balloon is compressing the helium, it will need to be bigger, since the density of the helium goes up as the pressure increases).At around room temperature and ordinary pressures, helium has a density of about 0.164 kilograms per cubic meter. Under the same conditions, air has a density of a little under 1.2 kilograms per cubic meter. For a ballpark estimate, therefore, we can say that a balloon with a volume of 1 cubic meter will lift roughly 1 kilogram, which makes the calculation easy: to lift a 175 lb (80 kg) person, you need an 80 cubic meter balloon, which if spherical would have a radius of 2.67 meters or a little over 8 feet 9 inches.A helium balloon 18 feet across should be sufficient to lift 175 pounds. Now you know why blimps are HUGE.

How much water is needed for an 80 lb bag of Sakrete?
An 80 lb bag of Sakrete typically requires about 2.5 quarts of water for mixing.
If there was 7.48 gallons in a cubic foot how much volume would 1lb of helium gas occupy?
That depends on the pressure inside the container. You can cram 1 lb of helium into any container, as small as you want. On the other hand, it'll always spread out and fill any container you put it in, no matter how large. So if you want to know how much volume a sample of helium will fill, you have to specify the pressure. By the way ... the temperature also affects the pressure of a gas, so you have to specify the temperature too.
What is Lift capacity for Hyster H80C Forklift?
8000 LB
How many watts of power does it take to lift 2204.622 lb?
To lift 2204.622 lb (1000 kg) with an acceleration of 9.81 m/s^2, you would need 9810 W of power.
