how much air do we need?

1 min = 35 liters The average adult male working at a moderate activity level inhales 16.8 cubic meters of air over the course of an 8-hour work day.

Add an additional 1.5 to 2.5 cups of water each day if you exercise. You may need to add even more if you work out for longer than an hour. You may need more water if you live in a hot climate. If you live at an elevation greater than 8,200 feet above sea level, you may also need to drink more.

As a general rule we advise you to buy an Air Conditioner with a minimum 7,000BTUs as this is the minimum required to cool a small room (18sq/m) on a hot day. Medium rooms (24sq/m) need around 10,000BTUs and larger rooms and office spaces (36sq/m) require around 15,000BTUs.

The size of your space determines how much cooling capacity you need. Budget air conditioners range from 5,000 BTU, which can handle about 150 square feet, to 12,000 BTU, enough to cover about 550 square feet. Naturally, air conditioners with higher capacities have higher price tags.

Safe Oxygen Levels For humans and many animals to sustain normal functions, the percentage of oxygen required to sustain life falls within a small range. The Occupational Safety and Health Administration, OSHA, determined the optimal range of oxygen in the air for humans runs between 19.5 and 23.5 percent.

An average person will breathe 0.5 (liters/breath) x 15 (breaths/minute) x 35,344,512 (minutes/lifetime), which equals 265,083,840 liters/lifetime. More or less 265 million liters of air.

At rest, an adult breathes 12–15 times per minute, inhaling and exhaling 0.4–0.5 L of air with each breath. The breathed air is altered in some respects: The exhaled air contains less oxygen, but more car- bon dioxide and more water vapor than was inhaled.

* Hold the tube, take a deep breath and blow until there is no air left in your lungs. * Measure how much air is in the bottle (count the marks). To calculate your lung capacity multiply the number of marks by 250 and then divide by 1000. It's a good idea to try this 3 times and work out the average from your results.

To properly blow out a sprinkler system, your air compressor needs to provide at least 20 cubic feet per minute. Most irrigation professionals recommend using at least 50 cubic feet per minute. Most air compressors will list their cubic feet per minute rating on the side of the tank.

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.

5,000 BTU air conditioners are recommended for rooms less than 200 square feet (ideally less than 150 square feet). The wattage of 5,000 BTU air conditioner units averages 446 to 580 watts (most of the units assessed for this average were window units, as 5,000 BTU split units are uncommon).

So breathe easy. The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level—a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)

The rule of thumb I work on is a minimum of 1l of air per l of water in your buckets. However, this is for single plants. I feel it is not good to have more than one plant per bucket in DWC.

That's why it's important to drink enough fluids. In climates such as the UK's, we should drink about 1.2 litres (six to eight glasses) of fluid every day to stop us getting dehydrated. In hotter climates, the body needs more than this.

To support the absorption of oxygen and release of carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter (about three tenths of a quart) of oxygen is transferred from the alveoli to the blood each minute, even when the ...

In most cases, it will require at least 50 mL of air to result in significant risk to life, however, there are case studies in which 20 mLs or less of air rapidly infused into the patient's circulation has resulted in a fatal air embolism.
