No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

Why must sling psychrometer be swung in order to obtain the wet bulb reading?
It is cooling by evaporation
Who invented the water thermometer?
Charles WingerThe Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.
What is the superheat?
17 to 20 degrees is normal.you should always check dry bulb at return air and outside temp to determine the correct reading
Can you control inside temperature of bulb when it is glowing.?
I hope temp inside the bulb can be control by varying the input voltage and monitoring it be Infra red thermometer. But it may possible that illumination of bulb get affected.
How do you increase accuracy in a liquid in glass thermometer?
There are several ways:use a liquid whose coefficient of thermal expansion is near constant,use a liquid with low vapour pressure,use a bulb with a relatively larger bulb and thinner stem,calibrate the thermometer carefully.
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.
Why is it advised not to hold the thermometer by its bulb while reading it?
The temperature of your hand affects the reading of the thermometer.
Why is it necessary to insulate the bulb on the thermometer went taking the superheat of an evaporator?
So you can get a correct reading
What is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
What is a glass bulb of a thermometer?
thermometer
Why must the sling psychrometer be swung to obtain the wet bulb reading?
It is swung through the air to speed up evaporation of water from the wet bulb thermometer.
A bulb thermometer gives an indoor temperature reading of 21 degrees celsius A digital thermometer in the same room gives a reading of 20.7 degrees celsius Which device is more precise?
i got this for science homework too
What will happen if you hold a mercury thermometer from its bulb?
is it dangeorous to hold a thermometer from its bulb
Does the wet bulb thermometer on a WBGT have to be wetted with distilled water?
It doesn't have to be distilled. A good reading can be obtained with tap water,
In a thermometer an indication the temperature is dropping is?
In a liquid thermometer the liquid will retreat towards the reservoir bulb at the end of the thermometer. In other types of thermometers - digital, dial, etc. - decreasing values of the reading are an indication that temperature is dropping.
How does a psychrometer work?
A psychrometer has two thermometers first off, second it can work by the bulb of the wet-bulb thermometer that has a cloth covering the moistened with water. Air is than blown over both thermometers. Because the wet -bulb thermometer is cooled by evaporation, its reading drops below that of the dry- bulb thermometer and dont let stalkers stalk you .. plus LOOK UP SKRILLEX ON YOUTUBE!! AWESOME!!!
