When wet bulb temperature and dry bulb temperature are equal?
for air water system wet bulb equals to dry bulb at 100 % relative humidity for that given temperature of air.
On a cold winter day the air temperature is 2C and the wet-bulb temperature is -1C What is the relative humidity at this location?
51%.... open to the Relative Humidity chart in the reference tables. the wet bulb temperature is -1C and the dry bulb temp. is 2C, making a difference of 3C. On RH chart, go down to 3C column (difference between the Wet bulb and dry bulb) until it intersects the dry bulb 2C. At this intersection is 51%
What is the instument used to find relative humidity?
barometer A barometer measures atmospheric pressure, not humidity. A hygrometer measures humidity.
How does a psychrometer measure relative humidity?
A sling psychrometer (or hygrometer) uses the difference in readings between a wet bulb thermometer and another with a dry bulb to measure the relative humidity. The bulb that is wet will cool by evaporation to the "dew point", which is the temperature at which the current humidity would be the maximum possible. Comparing that to the dry bulb (the general air temperature) on a comparative chart will yield the approximate relative humidity.
What would happen if a wet bulb had the same temperature as a dry bulb?
That means that there is 100% humidity. Normally evaporation from the wet bulb keeps its temperature lower than the dry bulb. At 100% humidity, there would be no evaporation, so they would show the same temperature.
What is the relative humidity when the dry-bulb temperature is C and the wet bulb temperature is C?
50 percent
When wet bulb temperature and dry bulb temperature are equal?
for air water system wet bulb equals to dry bulb at 100 % relative humidity for that given temperature of air.
What is the significance of wet bulb temperature?
dry bulb temperature simply tells us the temperature of dry air.but the comfort also depends on humidity ie. water vapour presents in the air.Wet bulb temperature measures the humidity in the air.Because the evaporation of water in the bulb wick depends on the relative humidity of surrounding air.
What is relative humidity reported as?
Relative humidity is reported in percentages. The percentage relates to the amount of water vapor air of a given temperature holds when it is saturated. So the humidity is reported as 50%, if the amount of water vapor in the air is half of what the air could hold at its current temperature.
What step should you follow to measure humidity with a psychrometer?
A sling psychrometer (or hygrometer) uses the difference in readings between a wet bulb thermometer and another with a dry bulb to measure the relative humidity. The bulb that is wet will cool by evaporation to the "dew point", which is the temperature at which the current humidity would be the maximum possible. Comparing that to the dry bulb (the general air temperature) on a comparative chart will yield the approximate relative humidity.
What is the relative humidity of a room having a dry bulb 72 degrees F and a wet bulb temperature of 59 degrees F?
answer is
On a cold winter day the air temperature is 2C and the wet-bulb temperature is -1C What is the relative humidity at this location?

How would you use a wet bulb thermometer and a dry bulb thermometer to find the relative humidity?
You would use both to determine the relative humidity.
How do you use a wet bulb thermometer and a dry bulb thermometer?
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 temperature reading on the wet bulb thermometer will drop. if the humidity is high only a little bit of water will evaporate from the cloth of the wet bulb thermometer and the change in temperature will be small.
What is the dewpoint when the dry-bulb temperature is 24 degrees celsius and the wet-bulb temperatrue is 15 degrees celsius?
8
What happens to the humidity as the differences of the dry and wet bulb increase?
the relative humidity will decrease.
What is the instument used to find relative humidity?
barometer A barometer measures atmospheric pressure, not humidity. A hygrometer measures humidity.
