What is the relationship between dry bulb temperature and relative humidity?
The evaporation is reduced when the air contains more water vapor. The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity (the air is at the saturation line).
When dry bulb temperature and wet bulb temperature are measured greater the difference between debit and WBT?
MCQ: When dry bulb temperature (DBT) and wet bulb temperature (WBT) are measured, greater the difference between DBT and WBT, greater the amount of water vapour held in the mixture. smaller the amount of water vapour held in the mixture. same the amount of water vapour held in the mixture.
What does it mean when the wet and dry bulb thermometers are the same temperatures?
Evaporation is an endothermic process, which means it absorbs heat, so the wet bulb temperature is lower than the dry bulb temperature or the same. If the relative humidity is 100 percent, which means the air can’t hold any more moisture, no evaporation occurs, and the wet bulb and dry bulb temperatures are the same.
What happens to the relative humidity as the difference between the dry bulb and wet bulb decreases?
The scientist subtracts the wet bulb reading from the dry bulb reading. The greater the number of degrees difference, the less water vapor is in the air, which means the relative humidity is lower. In other words, there is more room for the liquid water molecules to evaporate into gaseous water molecules.
What happens to relative humidity when temperature decreases?
Just as increasing the temperature decreases relative humidity, decreasing the temperature increases the relative humidity.
What is the relation between DBT and WBT if the relative humidity is 100% Mcq?
5. What is the relation between DBT and WBT if the relative humidity is 100%? Explanation: When the dry bulb temperature is equal to the wet-bulb temperature, then the relative humidity tends to be 100%.
What happens if the relative humidity is 100?
A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. If the air is at 100 percent relative humidity, sweat will not evaporate into the air.
What is the relation between dry bulb temperature DBT and wet bulb temperature WBT if the relative humidity is 100 %?
When relative humidity of the air is 100%, i.e the air is saturated, the dew point temperature (DPT) equals the wet bulb temperature (WBT), which is also equal to the dry bulb temperature.
