How does the principle that governs the operation of a psychrometer for determining relative humidity?
A psychrometer operates on the principle of evaporative cooling, which measures relative humidity by comparing the temperatures of two thermometers: a dry bulb and a wet bulb. The dry bulb measures the air temperature, while the wet bulb is moistened and measures the cooling effect of evaporation. When humidity is low, the evaporation rate is higher, causing the wet bulb temperature to drop significantly compared to the dry bulb. The difference in these temperatures can be used to calculate the relative humidity using psychrometric charts or formulas.
If the difference between a wet bulb and a dry bulb thermometer is great is the humidity low?
No, the humidity is high when wet and dry bulb temps are far apart.
How would youwould use a wet-bulb thermometer and a dry-bulb thermometer to find the relative humidity?
USE as the air passes over the wet bulb thermometer the water in the cloth evaporates. as the water evaporates the cloth cools. if the humidity is low the water will evaporate more quickly and the...
Which biome is very dry?
Desert biome is very dry, characterized by low precipitation levels and high temperatures.
What biome is hot in the daytime cool or cold at night very dry organisms are adapted to extreme temperatures and dry conditions?
The biome described is a desert. Deserts have high daytime temperatures, low nighttime temperatures, and very limited precipitation. Organisms in deserts are adapted to survive in extreme temperatures and dry conditions.
Why refrigerator has bulb and freezer don't?
Because of extreme low temperatures down to -45 degrees C in freezers when you open the door the warm air from outside will damage the bulb.
Is dry ice a liquid?
Dry ice is not a liquid. It is a solid form of carbon dioxide. Carbon dioxide changes from a gas to a solid at low temperatures, under pressure.
Will the relative humidity be high if the wet-bulb depression increases?
No, the relative humidity will be low if the wet-bulb depression increases. Wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature, and a higher wet-bulb depression indicates drier air.
Sapporo has its lowest temperatures in which month?
January is the coldest month of the year when low temperatures in Sapporo are recorded. Sapporo has a humid continental climate with hot summers and no dry season.
Why is ozone depletion going on mainly in Antarctica?
It is because of the low temperatures. Westerlies are also responsible for it.
Which natural event can dry out plants and cause wildfires?
A drought can dry out plants and create dry conditions that increase the likelihood of wildfires. High temperatures, low humidity, and dry vegetation can all contribute to the spread of wildfires.
What state does carbon dioxide exist in on earth?
Carbon dioxide exists in the gaseous state on Earth's surface. It can also exist as a solid (dry ice) at very low temperatures or as a liquid at high pressures and low temperatures.
