Sliding friction is when two objects slide across from one another. An example is sliding a book across a desk. It is also known as Kinetic friction.

Why does a desert cooler cool better on a hot dry day?
In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day.

Will a wetbulb cool down more on a dry or humid day?
A wet bulb will cool down more on a dry day because the dry air has a greater capacity to absorb moisture, resulting in more evaporation from the wet bulb and therefore a greater cooling effect compared to a humid day where the air is already saturated with moisture.
Why do people feel cooler on a hot dry day than on a hot humid day?
On a hot humid day the air circulation is heldup by the moisture density present in the air. the air gains weight and will not move . where as on a dry hot day the air is lighter and travels freely. * * * * * The air on a hot humid day holds much more moisture than on a hot dry day. As a result, your perspiration will evaporate much more quickly on a dry hot day and the process of evaporation will require heat equivalent to the latent heat of vaporisation. A lot of this heat will be taken from your body and that is why you will feel cooler.
Why does a desert cooler cools better on a hot dry day?
How Does it Work?The heart of an evaporative cooling system is the pad where the water evaporates and the air passing through the pads is cooled. A special water distribution system spreads water over the surface of the pad, ensuring a uniform supply of water to keep the entire air contact surface thoroughly wetted. Fans create a negative pressure, causing air to be drawn through the pads. Evaporation results from contact between air and water. A control system operates the water pump and the fan distributes the cool air.The relative humidity is lowest in the afternoon when the temperature is at its highest. And the lower the humidity, the better the evaporative cooling effect. In other words, the cooling effect is best when you need it the most.Source: www.bajarangs.com/whyevaporativecoolers.html
Do you think sweating cools you down more on a dry day or a humid day?
Sweating cools you down more on a dry day than on a humid day.
Why doe a desert cooler cool better on a hot dry day?
hummm i dont really know i think it is food
Why a cooler is more effective on a hot and dry day?
Sliding friction is when two objects slide across from one another. An example is sliding a book across a desk. It is also known as Kinetic friction.
When using a swamp cooler can you use a rheostat to control the motor speed?
A: A swamp cooler uses water flow to control temperatures as the water flow increases the transfer function increases. So yes it will effect the temperature. but for humans at the same time more water in the air will effect our perspiration and cooling in effect basically it will reach an equilibrium whereby more water will not cool us any further. A 70 degrees and 100 % humidity is hotter then 85 degrees dry heat
Do you sweat more on a hot dry day or a hot humid day?
You typically sweat more on a hot humid day because the high humidity reduces the rate at which sweat evaporates from your skin, making it feel like you are sweating more. On the other hand, on a hot dry day, sweat evaporates more easily, which can help cool your body more efficiently.
Does a dry climate have little vegetation hot summers and cooler winters?
Dry climate like hot summers and cooler winters do have little vegetation.
What is the climate of Arizona in the summer?
Hot and dry during the day, cooler during the night, unless you're in the mountains, in which case the weather is comfortable during the day and cold at night.
