Keeping your home at a comfortable temperature is an extremely important consideration for most homeowners. The term "CFM" is an acronym that stands for "cubic feet per minute," a term used to describe a fan's efficiency in terms of airflow. Determining the CFM of a room is a mathematical...
How To Calculate CFM For A Room? (Solved Example) Let’s say we have a big 1,000 sq ft room with standard 8 ft high ceiling. We want to calculate the CFM of a fan that will exchange all the air in such a room every 15 minutes (ACH = 4). We can use calculate fan CFM in t...
How to Calculate Round Duct Area to Square Feet Square footage. The size of your home and each room directly affects ductwork size. A professional will precisely measure your home's overall square footage as well as the square footage of each room. Cubic feet per minute calculation...
The volume of a particular gas that moves across a specific surface in a fixed amount of time is its flow rate. Similar to how the output of water moves from a faucet head, for example, in liters per minute or pints per second. The amount of gas leaving a tank may be in similar u...
I know how to find the lower flammability limit (LFL) and I know what my expected room temperatures will be. However, I do not know how to calculate the relevant concentration of the flammable materials. I'm guessing that this calculation is within the domain of mechanical design, and that...
RE: how to calculate the force created by liquid thermal expansion Unotec (Chemical) 8 Jul 08 16:24 Only if there is no room to expand, as in my gaden hose's pipe this last winter. If the vessel where the liquid is contained does not expand at the same rate and has a moving par...

The procedure to calculate the wavelength of sound (that is, the distance a sound waveform travels between its peaks) is dependent on the pitch of the sound and the medium the sound travels through. In general, sound travels faster through a solid than a liquid, and sound travels faster thr...
there may be as many as 100-200 people who survive for every completed suicide. Another statistic that is difficult to calculate is the number of people who are surviving family members, partners, or close friends of every victim of suicide -- also known as survivors of suicide. A low esti...
they also break it down into sensible, latent, and total. From the total cooling load, you can calculate the sf/ton I mentioned above. RightSuite doesn’t do it for you, but Elite’s software does. In the Project Report, they include a section calledCheck Figuresthat includes the sf/to...
