2018年10月12日 · Relative humidity is usually expressed as percentage (%). Degree of Saturation/Percentage Saturation Degree of saturation (m ) is the ratio of the humidity ratio of moist air (w) to the humidity ratio of saturated moist air (ws) at the same temperature and pressure. From Eqn. (2), Eqn. (6) becomes

2023年6月16日 · Answer: 60%. Explanation: Relative humidity is the ratio of the partial pressure of water vapor present in the air to the vapor pressure of water at a particular temperature, expressed as a percentage.In this question, we are given the vapor pressure of water (23.76 mm Hg) and the temperature (25 oC).

2020年4月23日 · Relative humidity is influenced by temperature and geographic location. Warmer air holds more moisture than cooler air, and warmer weather promotes evaporation. Areas with a lot of surface water, such as coastal areas and the Great Lakes region, have high humidity levels due to evaporation. Explanation:

2023年4月1日 · Humidity ratio = mass of water vapor / mass of dry air. First, we need to find the actual vapor pressure using the dew point temperature: From the steam table, the saturation vapor pressure at 20°C is 2.338 kPa. Using the formula for relative humidity: Relative humidity = (actual vapor pressure / saturation vapor pressure) x 100%

2021年9月10日 · Transpiration shows inverse relation with relative humidity and direct with Atmospheric temperature . Hence, (b) is incorrect. Transpiration increases with light intensity . Hence, (c) is incorrect . Transpiration shows inverse relationship both with Atmospheric pressure and relative humidity . Hence, (d) is incorrect .

Relative humidity can be calculated using a formula, Relative humidity partial pressure vapour pressure × 100 %. This can be explained in three cases, Assume partial pressure as p and vapour pressure as v. Case 1: When p v, then the temperature is high and relative humidity is low. this is called evaporation.

Relative humidity is the comparison between amount of moisture in air to the amount of air it can hold. Moisture in air are stored in the space between two air particles,and heat energy is stored in the surface of the air particles as the temperature increases then the …

2019年8月25日 · Relative humidity is the ratio of partial pressure of water vapour to the equilibrium water vapour pressure. Degree of saturation ranges from 0 to 1 and relative humidity ranges from 0 to 100. plz mark as brainlist

For heat, deserts near the equator can have temperatures well over 40 deg C. The relative humidity in Antarctica is often over 80%, so relative humidity there is often higher than relative humidity in the equatorial regions, but the air is so cold it holds far less water vapour per cubic metre than hot dry deserts do.

2019年10月21日 · At the same time, his cousin Roberta uses her sling psychrometer to measure the relative humidity near her house. The dry bulb temperature reads 58°F, and the wet bulb reads 50°F. What can you conclude from the values? A. The relative humidity is higher at Harry’s school than at Roberta’s house. B.
