What does wet bulb depression depend on?
Wet bulb depression depends on the humidity level in the air. It is the difference between the dry bulb temperature and the wet bulb temperature, and it indicates the cooling potential of evaporative cooling systems. A higher wet bulb depression indicates that the air is drier and has a greater capacity to absorb moisture.
Will the relative humidity be high if the wet-bulb depression increases?
No, the relative humidity will be low if the wet-bulb depression increases. Wet-bulb depression is the difference between the dry-bulb temperature and the wet-bulb temperature, and a higher wet-bulb depression indicates drier air.
The difference between wet-bulb and dry-bulb temperature is called?
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
What is a wet-bulb depression?
The wet-bulb depression (WBD) is the difference in temperature between the ambient air temperature (Ta) and the wet-bulb temperature (Tw), ie: WBD = (Ta-Tw), and is associated with the maximum possible lowering of air temperature (hence, the word "depression") that's possible by evaporation of water vapor into the air up to the 100% relative humidity point.
What would the total heat content of the air be if the outside fresh air conditions were 93F dry bulb and 74F wet bulb?
To calculate the total heat content of air, we need to consider both sensible heat (dry bulb temperature) and latent heat (wet bulb temperature). The wet bulb temperature indicates the amount of moisture in the air. By using psychrometric charts or equations, we can determine the enthalpy of the air at those conditions. The total heat content would be the sum of the sensible and latent heat components.
How does a wetdry bulb work?
The thermometers are the same, one's bulb is covered in thin cloth called a muslin. The muslin is connected to a water reservoir, and water "wicks" up the muslin, evaporates, and cools the thermometer. So the wet is always (or should be) lower than the dry bulb temp. From the difference (called the wet bulb depression) you can calculate dew point and relative humidity, from printed tables. If the air is dry the depression will be higher (as there is more cooling) while the temps will be close together if the air is moist.
How was a light bulb made?
A light bulb is made by creating a glass bulb, evacuating it of air, adding a tungsten filament, sealing the bulb, and then connecting it to a power source to produce light when heated. The process is carefully controlled to ensure the right conditions for generating light efficiently and safely.
Design condition of air conditions?
I think you are asking about "standard" air. It is 80 degrees F. dry bulb, 67 degrees F. wet bulb. (about 50% relative humidity). 29.92 barometric pressure. its a specific case! In common, design condition of air condition depend on velocity air, temperature ,humidity, type of space condition air. you can refer on ASHREA.
How would youwould use a wet-bulb thermometer and a dry-bulb thermometer to find the relative humidity?
USE 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...
What did you observe that allowed you to infer that air is matter?

Why does heat from the top of the bulb feels different from the heat on the side of the bulb?
The heat from the filament radiates in all directions inside the bulb (as there is no air for convection). Once the heat reaches the glass the heat is now transmitted by both radiation and convection.Hot air rises so the air on the side of the bulb is heated and it rises up, it is now replaced by cooler air which needs to be heated. So the air on the side of the bulb is colder than the air on top. If you hand is on top of the bulb it will be heated by the air raising from the side as well as the top.
Could an ordinary glass can serve as the glass bulb of a bulb?
Sure. But before you can use it to provide light, you need to find a way to take all the air out of it, and seal it so that no air gets back in. If air gets into a light bulb, the bulb immediately burns out.
