What else can I help you with?
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?
Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading and providing inaccurate results. It's recommended to hold the thermometer by the stem to prevent any external heat sources from interfering with the measurement.
What will happen if you hold a mercury thermometer from its bulb?
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
Why is the wetbulb thermometer read lower than The dry bulb thermometer?
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
Which one is always higher wet bulb temperature or dry bulb temperature?
The wet bulb temperature is always lower than the dry bulb temperature. The wet bulb temperature is the temperature taken by a thermometer covered in a wet cloth and exposed to moving air, and it reflects the evaporative cooling effect.
Why you should not hold the thermometer by its bulb?
Holding the thermometer by its bulb can transfer heat from your hand to the bulb, affecting the temperature reading. This can lead to inaccurate results. It's best to hold the thermometer at the opposite end to prevent any interference with the measurement.
Why is the bore on a clinical thermometer narrower directly above the bulb?
The bore of a clinical thermometer is narrower directly above the bulb to slow down the expansion of mercury and provide a more accurate reading. This design helps to prevent sudden changes in temperature from affecting the reading, making the thermometer more precise.
why is it always the bulb of the thermometer that breaks?
The bulb of a thermometer is usually made of glass to allow for expansion and contraction of the liquid inside. When the thermometer is subject to sudden changes in temperature, the glass can crack or shatter due to thermal stress, causing the bulb to break.
What is the connection between the reading and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.
Where is the capillary tube and bulb in a thermometer?
The capillary tube is the hollow opening inside the thermometer that the liquid rises or lowers in so that you can read the temperature. The bulb is the bottom portion that holds the liquid and the part you use for contact to get a temperature reading. Calvin B.
Why must the bulb of the thermometer be submerged in the water?
The bulb of the thermometer must be submerged in the water because that is where the temperature of the water is accurately measured. The bulb is the part of the thermometer that contains the temperature-sensitive material, such as mercury or alcohol, which expands or contracts depending on the temperature of the water. This expansion or contraction is then displayed on the thermometer scale, giving an accurate reading of the water temperature.
