What is the relative humidity when the dry-bulb temperature is C and the wet bulb temperature is C?
50 percent
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 happens to the humidity as the differences of the dry and wet bulb increase?
the relative humidity will decrease.
What happens when the wet and dry bulb thermometers are close together?
The relative humidity is higher.
What equipment would you need to perform an experiment that measures relative humidity?
wet bulb and dry bulb temps.
What is the dew-point when the dry bulb temperature is 20C and the relative humidity is 17?
at 17% relative humidity the dew point is -5.8C at a dry bulb of 20C
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 the relative humidity of a room having a dry bulb 72 degrees F and a wet bulb temperature of 59 degrees F?
answer is
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.
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%

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.
What instrument measures relative humidity using wet-bulb and dry-bulb thermometers?
Hygrometer
What is the use of dry and wet bulb tenperature?
How you would use a wet-bulb thermoter and a dry-bulb theremometer to fine the relative humidity?
