It varies on wind speed but is equal or greater than the required exhaust vents on the market when used at the soffits. CFM is very hard to compare apples to apples because of all the different variables. Everything would need to be exactly the same for the tests: Outside and Inside Temp., Pressure, wind, same ridge vent, same shingles, same inside living space conditions, same sun rays, etc. etc. etc……..That is why we feel that the industry has chosen NFA to compare products.

BTU rating is important if you are going to install a properly sized A/C unit to cool a certain well insulated area. CFM is important if you are going to install a properly sized large 110-volt Evaporative Cooler on the roof or in the side wall of a well insulated building so you can build up a negative pressure within a certain area so you can cool the entire area. Negative pressure cannot typically be built up in an area by using the limited resources of a 12-volt Portable Cooling Device. See similar questions...

If we start with 1000 cubic feet of natural gas (and assuming it is pure methane or CH4) at STP (standard temperature and pressure, i.e., temperature of 273&#176K = 0&#176C = 32&#176F and pressure of 1 atm = 14.7 psia = 760 torr), and burn it completely, here's what we come up with: Since 1 mole of a gas occupies 22.4 L at STP, 28316.85 L of CH4 contains 28316.85/22.4 = 1264.145 moles of CH4 (each mole of CH4 = approx. 16 g) One mole of CO2 has a mass of approx. 44 g, so 1264.

The ER1200 makes 1200 liters of gas per hour. There are 28 liters in a cubic foot. So the ER1200 will make 42.85 cubic feet per hour. See similar questions...

The amount of air required by the gas combustion burner on the Tornado 60 Washing machine. This machine was shipped with a 380,000 BTU/hour capable burner. The amount of air required to burn natural gas is a fixed amount. Adding in about 3% excess air for safe combustion the rule of thumb is that it takes 10 cubic feet of air for every cubic foot of gas. Unless you know the BTU/cubic foot of natural gas in your area another rule of thumb is to use 1000 BTU/cubic foot. See similar questions...

The CFM (Cubic Feet per Minute) is the measurement of how much air passes through the unit. For the HealthMate, the HealthMate+ , and the Allergy Machine™ the fan CFM is 400 cfm on high and 75cfm on low. The HealthMate Jr™ is 200 cfm on high and 50cfm on low. See similar questions...

Cubic feet per minute - a unit of measure used in air infiltration testing, e.g., "maximum .10 cfm per square foot of window area." See similar questions...

This water meter measures household water usage in cubic meters, with three decimal places plus a dial showing a fourth. There are 1000 liters in a cubic meter, so the seven-digit number is in liters. The liter was originally defined in 1795 as a volume equal to a cubic decimeter, just as it is now. But in 1901, the liter was redefined to be the volume occupied by a mass of 1 kilogram of pure water, at its maximum density and at standard atmospheric pressure. See similar questions...

The rdsamp-O-Matic is intended to offer short samples of data in text form without the need for anything more than a web browser. It is not intended to be a method for obtaining large amounts of data. If you need more than a minute, we strongly recommend using any of the other methods for reading signal files described above, which do not impose any limit on the amount of data that can be obtained.

Walk barefoot. Walk barefoot some more. Go barefoot everywhere you can. Your soles, foot muscles, ligaments, and tendons are like any other parts of your body: you have to use them to develop them, otherwise they will atrophy. Note that you wouldn't need to build up your feet if you went barefoot from birth as nature intended. What you're actually doing by "building them up" is getting them back to their natural state.

The symptoms of arthritis which may include joint swelling, pain, tenderness, heat, redness, and/or limitation of motion, plus early morning stiffness, and skin rashes - often show up first in the feet? Since arthritis attacks the joints - and each of your feet has 33 joints - it is easy to understand how arthritis can seriously affect foot function. Fortunately; there is much you can do offset these effects on your feet and stay as active as you want to be. See similar questions...

CFM stands for “Cubic Feet Per Minute”. It is a measure of the blower’s air movement performance. The CFM performance of all Tempest Blowers is tested and certified by a third party organization, Air Movement and Control Association, called AMCA. This ensures that our customers receive accurate performance information. See similar questions...

A complete listing of the CFM ratings for all Tempest blowers can be found on our web site. Go to the main page and click on the product link that says “Blowers”. This information is also available in the current Tempest product catalog and can be requested by calling Tempest Customer Service. See similar questions...

There is a great deal of confusing and misleading information being circulated as "airflow data." Sometimes the airflow is stated as "free air" or is given without reference to the static pressure (SP). Both ignore the flow restrictions imposed by vacuum hose, filters and other system components. Other published rates have never been tested or verified using established industry testing protocols. See similar questions...

Certification is valid for three years. CFMs must demonstrate a continued commitment to growth and excellence by earning a required number of maintenance points in at least two of the following categories: See similar questions...

Cubic refers to the VR panorama format which represents the view around the observer as six cube faces (four around, one above and one underneath). The cubic format is the one used by the latest versions of QuickTime VR, which is arguably the most popular and highest quality of VR software around. See similar questions...
