Why does the desert cooler not work in the rainy season?

The desert (swamp) cooler depends upon evaporation of water for cooling. During the rainy season the air is already pretty much saturated with water vapor so little water evaporates from the cooler and they become inefficient. They are most efficient when the relative humidity is below 20%.


Why do houses in the desert have a flat roof?

Houses in the desert often have flat roofs to accommodate the region's climate and architectural style. Flat roofs help with efficient rainwater drainage during rare storms and allow for the installation of rooftop features such as solar panels or terraces for outdoor living. Additionally, they provide better insulation against the intense heat and can reflect sunlight, keeping the interior cooler. This design also aligns with modern and minimalist aesthetics commonly found in desert architecture.


Can mean effective pressure of an automobile engine in operation be less than the atmospheric pressure?

Yes, the mean effective pressure (MEP) of an automobile engine in operation can be less than atmospheric pressure, particularly in engines operating under certain conditions, such as during idling or when experiencing a vacuum in the intake manifold. This situation can occur when the engine is not generating sufficient power or when the throttle is partially closed, leading to reduced intake air pressure. However, for efficient power generation, engines typically operate at MEP values greater than atmospheric pressure during normal operation.


What is made out of polystyrene?

Ordinary CD jewel cases.Expanded Polystyrene (EPS) Foam Products From Foam Cups To Foam Coolers To Houses And Highways!Expanded Polystyrene is the core material used for making thousands of different products, everything from foam coolers like we make at LoBoy EPS Foam Coolers in Fort Walton Beach, Florida, to floating boat docks, to custom home construction, highway and bridge construction, cups and party-ware, cd cases and protective packaging, plus EPS foam is very popular in Cold Chain Shipping (using eps foam shipping coolers to ship food across long distances to keep the food (or medicine) cold during transit). EPS foam is even used for furniture, home and business decor (there are some really beautiful architectural examples to be found in web searches).The reason for this is that it is an environmentally friendly, moldable plastic derived from crude oil. Of course, it's only environmentally friendly (as with anything) when it is not manufactured in combination with non-friendly stuff such as when a manufacturer ruins its recyclability by coating it with painted logos that are toxic. Non-toxic paints are best, but even that can interfere with practical recycling because you take a white material and mix in paint and when it's recycled you get a gnarly rainbow that you have to try to reuse. Better to use stamping directly into the EPS foam or just use adhesive labels. That way, the foam is completely reusable.At the LoBoy Foam Cooler company, we always recommend that people stop throwing away EPS foam products and start setting it aside until they have enough to take to be recycled. It's better for the planet (why make trash when you can convert trash to treasure?) and it helps create jobs.


Why grey cast iron is used for engine block?

Grey cast iron is commonly used for engine blocks due to its excellent castability, good wear resistance, and ability to dampen vibrations, which enhances engine performance and longevity. Its graphite structure provides effective thermal conductivity, helping to manage engine heat. Additionally, grey cast iron is relatively cost-effective and offers sufficient strength and rigidity to withstand the stresses encountered during engine operation.

How AC is better than desert cooler?

On humid days, such as during the rainy season, swamp (desert) coolers are not very efficient at cooling the air. Air conditioners are not affected by high humidity.


Is there moist air in the desert?

High humidities only occur during the rainy seasons of a desert. The rest of the year is quite dry.


What is the average temperature during all four seasons in the desert biome?

There are over 2 dozen major desert regions of the world, each with its specific climate data. Please name a particular desert.


Does the desert get evaporation?

Deserts have a very high evaporation rate. It can approach an inch per day during the hottest and driest seasons.


Why doesn't the desert have a waterfall?

To have a waterfall, you need a stream or river that runs with water throughout the year. Few occur in the desert. There are waterfalls in the desert but they are seasonal and only flow during rainy seasons or with snow melt from surrounding mountains.

Would frost wedging me more effective in cool high desert areas or where the subsoil is permanently frozen?

It is the feeze/thaw cycle that makes frost wedging really effective as an erosive force. Desert areas that are warm during the day and freezing at night experience more wedging than permafrost areas.


Why desert cooler are not effective during rainy season?

A desert cooler, also called a swamp cooler, depends on low humidity and evaporation to cool the air. It loses efficiency when the humidity is high, such as during the rainy season. Less water will evaporate when the air is already nearly saturated with water.

Why does it rain during war?

Because the seasons are the seasons. It rains when there is no war also.


Why is it always hot in a desert?

There are hot deserts and there are cold deserts so it is not always hot in a desert. The Antarctic Desert stays below the freezing mark even in summer. Some deserts are hot during the day but get quite chilly at night.
