How do you write cubic feet per second?
How do you write cubic feet per second?
Cubic feet per second (cfs): * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second. * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water.
What does cubic feet per second mean?
A cubic foot per second (also cfs, cu ft/s, cusec and ft³/s) is an Imperial unit / U.S. customary unit volumetric flow rate, which is equivalent to a volume of 1 cubic foot flowing every second.
What is the weight of air for the entire atmosphere?
about 5 million billion tons
How much does 1 square inch air weigh?
about 15 pounds
Which are the two main components of air?
Solution: The main components of air are: Nitrogen. Oxygen….Composition of air is:
- Nitrogen – 78%
- Oxygen – 21%
- Carbon dioxide – 0.03 %
- Inert gases – 0.9%
What are main components of air?
The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen.
What are the 3 components of atmosphere?
Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
What are the three major components of the air you breathe?
Standard dry air, which is mainly composed of three gases: nitrogen (about 78%), oxygen (about 21%), and argon (about 1%). Together, these three gases make up 99.96% of dry air.
Why the air is invisible?
Air looks invisible because it sends very little color to our eyes. Air is a mixture of gases, mainly nitrogen and oxygen, with small molecules that are far apart. Wavelengths of light may pass by these molecules without hitting them.
What air do you inhale?
Inhaled air is by volume 78% nitrogen, 20.95% oxygen and small amounts of other gases including argon, carbon dioxide, neon, helium, and hydrogen. The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount.
How do we get air?
Air flows in via our mouth or nose. The air then follows the windpipe, which splits first into two bronchi: one for each lung. The bronchi then split into smaller and smaller tubes that have tiny air sacs at their end called alveoli. We have millions of alveoli in our lungs!
What are the 10 uses of air?
Important Uses of Air
- Sustain life and growth.
- Combustion.
- Maintaining Temperature.
- Supplier of Energy.
- Photosynthesis.
How do we get oxygen from air?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air.
