What else can I help you with?
Is the wet bulb thermometer reading always higher than a dry bulb reading?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
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
How do you use hygrometers?
Fill the water bottle and screw it on to the instrument. Then hang the hygrometer (by the loop at the top) on a wall or a tree, for instance, for at least five to 10 minutes before taking the measurements. Ideally the instrument should be in a well-shaded spot or in a Stevenson screen (refer to "Making your own weather station" in Section 4: Contacts and further information). The instrument contains two alcohol-in-glass thermometers with a scale of minus 10 to plus 110 degrees Celsius, in 1 degree increments. The end of the 'wet-bulb' thermometer is covered with a damp cloth dipped in water. The other thermometer is the 'dry-bulb'. 6 Record the wet-bulb and dry-bulb temperatures. 6 Calculate the wet-bulb depression - the dry-bulb temperature minus the wet-bulb temperature. 6 Determine the relative humidity (%) using the table (reverse page). Read down from the wetbulb depression and across from the dry-bulb temperature. do's and don'ts Be careful with the instrument. The thermometers are made of glass and can easily break. Empty the water bottle before returning the hygrometer to its box. how it works The hygrometer works on a similar principle to the whirling psychrometer. The main difference is that the hygrometer is not rotated, so evaporation from the damp cloth around the wet-bulb thermometer occurs more slowly.
Dry bulb temp is the?
The ordinary thermodynamic temperature of the air, what you would measure with a regular thermometer. This is in contrast to the wet bulb temperature, which is the temperature reached by a wet surface. A classical weather station uses a sling hygrometer to measure the two. This is a pair of thermometers, one of which has a wet covering, something like a sock that can be dipped in water. By measuring both of these the humidity can be determined. Temperature of the free air as measured with a dry thermometer on a sling psychrometer over a grassy surface at a height of approximately 6 feet (1.8 meters).
What is different between dry seal and wet seal?
well one is dry and one is wet
What is the dew point temperature when the dry bulb temperature is 24 degrees Celsius and the wet bulb temperature is 22 degrees celsius?
The dew point temperature is 21 degrees Celsius when the dry bulb temperature is 24 degrees Celsius and the wet bulb temperature is 22 degrees Celsius.
What is the approximate dewpoint temperature of the dry-bulb temperature is 26 Celsius and the wet-bulb is 21 Celsius?
The approximate dewpoint temperature can be calculated using the difference between the dry-bulb and wet-bulb temperatures. In this case, the difference is 5 degrees Celsius. The dewpoint temperature is approximately 21 degrees Celsius.
What is the dewpoint when the dry-bulb temperature is 24 degrees celsius and the wet-bulb temperatrue is 15 degrees celsius?
The dewpoint in this case would be approximately 12 degrees Celsius.
What is the relative humidity on a psychrometer if the dry-bulb reading is 8 degrees Celsius and the wet-bulb reading is 7 degrees Celsius?
To determine the relative humidity, we need a psychrometric chart that relates wet-bulb and dry-bulb temperatures. Without that information, we cannot provide the exact relative humidity at those temperatures.
What is wet and dry bulb thermometer units measured in?
Well it is the same as what you measure a thermometer with which is Celsius and Fahrenheit which is C and F
What is the wet bulb depression if the dry bulb is 20 and the wet bulb is 17?
15
What does a wet bulb and a dry bulb measure?
A wet bulb measures the temperature after water evaporation allows to cool and a dry bulb measures air temperature.
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?
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.
What would the dew point temperature be when the wet and dry bulb temperature are the same?
the "current" temperature, ie, the temperature at which wet bulb and dry bulb are the same. when the wet bulb and dry bulb temperaturs equalized the dew point emperature equals them, because the air is saturated now.
Is The wet bulb thermometer reading is always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
Is the wet bulb thermometer reading always higher than the dry bulb?
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
