What is atmospheric pressure in pounds per square foot?
The standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa (‘pascals’) or 1013.25 millibars or hectopascals. It is equivalent to 760 mmHg (torr), 14.696 psi. This tool converts atmospheres to pounds per square foot (atm to psf) and vice versa. 1 atmosphere = 2116.2166236739 pounds per square foot.
How many pounds per square inch is the atmosphere?
We know that air weighs 14.7 psi or pounds per square inch at sea level – meaning about 15 pounds are pressing down on every square inch of you. In other words, that’s about the weight of car pressing down on you all the time!
How do you convert atm to psf?
To convert an atmosphere measurement to a pound per square foot measurement, multiply the pressure by the conversion ratio. The pressure in pounds per square foot is equal to the atmospheres multiplied by 2,116.218862.
How do you calculate pounds per square foot?
Divide force by area to calculate the pressure exerted. Continuing with the example, divide the elephant’s 5,940 lbs by 3.14 square feet to calculate the pressure of 1,891 pounds per square foot. Divide the little girl’s 55 lbs by 0.0009 to calculate her pressure of 61,111 pounds per square foot.
How much is a pound force?
One pound-force is defined. as the force required to accelerate an object with a mass of 1 pound-mass at a rate of 32.174 ft/s2. The number 32.174 comes from the acceleration due to gravity on Earth A pound is a unit measurement of weight used in systems of measurement. …
What is the density of air in LB ft3?
0.0765 lb/ft^3
In Metric units: 1.225 kg/m^3. In Imperial units: 0.0765 lb/ft^3.
How do you convert pounds to atmospheres?
To convert a pound per square inch measurement to an atmosphere measurement, multiply the pressure by the conversion ratio. The pressure in atmospheres is equal to the pounds per square inch multiplied by 0.068046.
What is the weight in pounds of the Earth’s atmosphere?
This gives us 7.93*10^17 square inches on the earth. Multiplying this by 14.7 pounds per square inch says that the atmosphere weighs about 1.17*10^19 pounds (or about 11,700,000,000,000,000,000 pounds)! That’s a lot of air!
What is normal air density?
1.293 kg/m3
Normal condition of gas is kg/m3 due to it’s volume can be changed by temperature and pressure. at iupac standard temerature and pressure (0 °c and 100 kpa), dry air has a density of 1.293 kg/m3.
How much is a pound-force?
How do I calculate pounds?
Weight converter formula (lbs, kg)
- Pound (lbs) / 2.2046 = Result in Kilograms (kg)
- Kilograms (kg) x 2.2046 = Result in Pound (lbs)
- 100 pounds (lbs) / 2.2046 = 45,36 kilos (kg)
- 100 kilos (kg) * 2.2046 = 220,46 pounds (lbs)
