CFM stands for cubic feet per minute. Oftentimes the true rate of an air compressor is misrepresented by manufacturers. Because of this, the only way to determine the real CFM of your air compressor is to test it yourself. Don't be fooled by false advertising any longer–follow these steps...
The good news is that most HVAC manufacturers make it easy to determine the nominal capacity of your air conditioner. It’s in the model number. Go outside and find the outdoor unit, that metal noisemaker hidden away on the side or the back of the house. It’ll look something like the...
Divide the result by 3.413 — a constant figure — to determine the BTUs per hour. To cite the example in Step 2, divide the 320 watts by 3.413 to get 93.76 BTUs per hour. Multiply the BTUs per hour by the number of hours the device runs to determine its total BTU output. To co...
BTU stands for British Thermal Units, a means of measuring heat and energy. One BTU equals the amount of energy required to heat one pound of water by 1 degree Fahrenheit. The BTU output measures how much heat or other energy a given appliance is generating — very useful when determining ...
and savings can be gained if the operation can be supplied more efficiently through optimization measures. To be able to initiate improvement projects, we must first calculate how much air we are wasting. When we know the answer we can make a business case to determine if the expense and eff...
When sizing a replacement system, I ask the client to provide cycle timing data, which I explain how to do. From that, I can determine the load (and thus size the replacement system) with greater accuracy than the most precise load calc. ...
To determine the exact CFM your sprinkler system can handle, find the gallons-per-minute (GPM) rating of each sprinkler head. Divide the total GPM of each zone by 7.5 to find the proper CFM of air pressure for the compressor. Then, adjust the pressure valve on the compressor to no more...
While sprinkler winterization should only be a half-day project, inexperienced homeowners might find it difficult to locate valves and determine how much air should be used during the blowout process. If this is your first DIY winterization, consult with a professional first to avoid costly mistakes...
6. A dialogue box will appear for you to enter your custom flow meter details. Make sure you enter the calibration details for your custom, pulse-based flow meter. Please refer to the manufacturer specifications to determine the calibration. Otherwise, you will not receive accurate readings to ...
This will all be influence on your air supply sources capability of you apparatus? Please note its not all about higher CFM numbers? You will learn more as you go along the flow testing path. Big holes flow big numbers but don't make big power! I have already responded to another one ...
