For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 grams (.6 ounces) of water. This would be a state of saturation, otherwise k
While you crank up your HVAC system, it’s best to use a ‘smart’ solution to make it as energy efficient as possible and maintain the best possible temperature! You can either use a programmable thermostat for a ducted system or a smart AC controller for a mini-split, window or ...
When thinking conceptually of water vapor as a gas, it's easy to define relative humidity. Relative humidity (RH) can be defined as the ratio of the partial water vapor pressure (Pw) to the water vapor saturation pressure (Pws) at a particular temperature: ...
Wet and Dry Bulb Temperature To predict how much a swamp cooler will cool the air, you need to know the wet and dry bulb temperature. The dry bulb is easy — it's just the regular temperature of the air. The wet bulb temperature tells you the temperature of adiabatic saturation, which...
Well, go do that last one. Don’t you really want to understand psychrometrics? I’m giving you plenty of opportunity to avoid accidentally seeing the answers here. OK, here you go. 1. On a cold rainy day, outdoor air leaks into a house and warms up to room temperature. What happe...
Over time the condensation leads to mold growth. This temperature difference can be readily observed with a thermal imaging camera, which will show a corresponding cold spot in the exact location of the mold growth. The solution is two-fold. Lower the humidity in the home and improve the ...
(1−ϕ)δckw+hkc]−1,where ΔT is the degree of subcooling; Tsat is the saturation temperature of the water vapor; hfg is the latent heat of vaporization; hi is the interfacial condensation heat transfer coefficient; δc is the thickness of the conformal hydrophobic coating; h is ...
“If generally rising temperatures, decreasing diurnal temperature differences, melting glacial and sea ice, smaller snow extent, stronger rainstorms, and warming oceans are not enough to persuade you that man-made climate is occurring, what evidence would be?” ...
