Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the poss...
14世纪晚期,“潮湿状态或质量”,来自古法语 humidité, umidité “潮湿,湿度”,源自拉丁语 humiditatem(主格 humiditas),源自 humidus “潮湿的,湿润的”(见 humid)。在气象学中,“与当前条件下饱和所需量相比,空气中的水分含量的度量”,始于1820年(完整短语 relative humidity 在1819年已出现)。
the wear coefficient is highest under dry pressurized air (RH ≤ 5%) and under high relative humidity values above 45%. At intermediate RH, the wear coefficient
For example, if the air temperature is 75 degrees Fahrenheit (24 degrees Celsius) and the relative humidity is zero percent, the air temperature feels like 69 degrees F (21 C) to our bodies. If the air temperature is 75 degrees F (24 C) and the relative humidity is 100 percent, we f...
(75% RH) for 12 h. The volume decreased by 24%, compared to the initial droplet volume when the humidity decreased to 15% RH for 12 h. This result indicates that the water content of the aqueous extract is strongly dependent on the relative humidity of surrounding air, and supports...
6. When it comes to humidity, what is the difference between absolute and relative humidity? The temperature is the difference between relative and absolute humidity. The former indicates the moisture content of the air without respect to temperature, whereas the latter indicates the moisture content...
The results show that the air temperature around and directly above the heater is the highest and the corresponding relative humidity is the lowest. Then, the air temperature gradually decreases, and the relative humidity increases with the lateral flow of air. When the ambient temperature increases...
Meet the highest demands: cutting-edge technology from Testo Air humidityis one of the most important measurement parameters. Depending on the application, different performance requirements are made when it comes to a humidity meter. That is why Testo offers an unbeatable diversity of instruments: ...
The grating is modified by an electrostatic self-assembly technique. When exposed to different humidity levels, the thin film of silica nanospheres changes its optical properties, which can be translated into a shift of the resonance wavelength of the fiber grating. In a relative humidity range ...
