We usually set the fan speed to keep the temperature rise of the air passing through the system between roughly 40F-65F depending on the age and efficiency of your system. So, return air temperature may be 70F which means that the supply air measured in the furnace would be 110F to 135F.
exists and is an alternate of . Carbon dioxide is denser than air. The density of carbon dioxide is 1,977 g/L at 0 0C and standard pressure. The density of air (the so called International Standard Atmosphere) is 1,225 g/L. Carbon dioxide is denser than air. <br /> The density of carbon dioxide is 1,977 g/L at 0 0C and standard pressure. <br /> The density of air (the so called International Standard Atmosphere) is 1,225 g/L.
What are the key differences between carbon monoxide and carbon dioxide? Both of these gases have a lot of similarities â both CO2 and CO are odourless and tasteless. The critical chemical difference is that CO2 contains one molecule of carbon and two molecules of oxygen, whilst CO has one carbon and one oxygen molecule. Carbon dioxide is non-flammable, whilst carbon monoxide is not â we certainly wouldnât encourage you to light a match in order to determine which gas is which.
