Answers of questions given in the log sheet (a) The heat gain is the air stream in the pre-heater and re-heater sections and compares it with the electrical readings. (b) The percentage of outdoor air that is introduced into the unit at different damper settings....
The paper presents the results of cobalt corrosion tests in air at different temperature and humidity values. It was demonstrated that corrosion losses in cobalt at temperatures of 20 and 30 °C and relative humidity of 70, 80, and 95% are insignificant. However, the rate of cobalt corrosion...
lower than that of the face, and in dry air, 6° lower, owing to the cooling effect of increased sweating.The gross mechanical efficiency fell off slightly at temperatures above 70 or 75° F. It was affected by the dry-bulb temperature of the air as well as the wet bulb, but not ...
Weather is affected by temperature and humidity. Weather fronts usually form when bodies of air have different temperatures and densities. Fronts generally generate weather outside the tropics. Answer and Explanation: A large body of air with the same temperature and humidity is an air m...
A novel technique for inferring RH was also attempted in which kaolinite clay samples were placed at different locations throughout the cave, and at different elevations above the cave floor at a single loca- tion, and allowed to equilibrate with the cave air. Subsequent laboratory analysis of ...
By means of this apparatus, two common synthetic fibres, polyester fibre and nylon 6, were fatigue-tested in air at various temperatures and humidities. For comparison, experiments were also performed in tap-water and sea-water at different temperatures. The results indicate that the fatigue ...

ofrelative humidityto a particular application depends on knowing both the dry-bulb temperature as well as the RH. For example the amount of moisture in a water-air mixture at 80% RH at 40°C is different from the amount of water vapor in a water-air mixture at 80% RH at 10°C (...
Visual Basic Python DIAdem ANALYSIS>Geo Functions> Relative Humidity Use this dialog box to calculate the relative humidity from the absolute humidity and the temperature. The relative humidity must not exceed 100%, because the air is otherwise supersaturated. ...
Such a good agreement between results suggested the suitability of the Boltzmann distribution model for describing the conductivity of SFHI at different temperatures. 2.5. Quantitative relationship of σ-RH As mentioned above, the proton transport path was provided by water in the system. Therefore, ...
