What else can I help you with?
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
Is a tank a pressure vessel?
I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
What is difference between injection rate and injection pressure?
The injection rate is the number of injections. The injection pressure is the pressure the injection is under.
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.
How much bar needed to convert air to liquid under pressure?
Initially, a minimum of 5.2 bar is needed to convert air to liquid under pressure. This pressure is for the initial process. For the final process, less than 1.7 bar is needed.
What is regelation?
Regelation refers to melting under pressure as well as freezing under reduced pressure.
When is physics used in desalination?
Physics is used in desalination when understanding processes like osmosis, reverse osmosis, and thermodynamics, which are fundamental to desalination technology. These processes involve the movement of water across membranes under pressure differentials and the utilization of energy for separation, making physics a critical aspect of the desalination process.
Why Glycerin is distilled at reduced pressure?
glycerin is distilled at reduced pressure because it has boiling point of 290 degree celsius under atmospheric pressure it slightly decomposes but under reduced pressure it distills unchanged
What benefit does one obtain by carrying out the distillation under reduced pressure?
Distillation under reduced pressure allows for the separation of compounds with higher boiling points at lower temperatures, preventing thermal degradation. It also helps to increase the efficiency of the distillation process by reducing the energy required for vaporization. Additionally, reduced pressure distillation can improve the purity of the distillate by minimizing side reactions.
How does soda fizz?
The carbon dioxide (CO2) in carbonated beverages is dissolved in the water under pressure and result in a bubbly fizz which is the CO2 being released as the pressure is reduced.
Describe vacuum drying method under reduced pressure?
In vacuum drying, the material is placed in a chamber where air and moisture are removed by creating a reduced pressure environment. This helps lower the boiling point of water, allowing it to evaporate more easily from the material at lower temperatures. The reduced pressure also accelerates the drying process by promoting faster moisture removal.
What is formed when swamp plants are buried under pressure for a very long time?
When swamp plants are buried under pressure for a long time, they may eventually transform into coal through a process called coalification. This process involves the decomposition of plant matter under high pressure and temperature, resulting in the formation of coal deposits.
How do plants grow under high atmospheric pressure?
Plants can still grow under high atmospheric pressure, although extreme pressure levels could impact the rate and quality of growth. The high pressure could affect the plant's ability to absorb nutrients and water, leading to stunted growth or other physiological changes. However, some plants, like deep-sea species, have adaptations that allow them to thrive in high-pressure environments.
Why does the boiling temperature of water decrease when the water is under reduced pressure such as it is in a higher altitude?
At higher altitudes, there is reduced atmospheric pressure, which leads to a lower boiling point of water. This happens because with lower pressure, it is easier for water molecules to escape into the air as vapor. Therefore, at higher altitudes, water reaches its vapor pressure (boiling point) at a lower temperature than at sea level.
How does gas compress under different pressure conditions?
Gas compresses under different pressure conditions by decreasing in volume when subjected to higher pressure. This is due to the gas particles being forced closer together, resulting in a denser and more compact arrangement. Conversely, when the pressure is reduced, the gas expands and occupies a larger volume.
Describe crude oil?
The plants and animals that existed and lived millions of years ago decompose and overtime are buried under the earth, there they are under pressure. As more and more pressure is applied, they become a fossil fuel.
Why must nitrogen be used only with oxygen under pressure?
Nitrogen should be used with oxygen under pressure to prevent the development of decompression sickness. When breathing high-pressure oxygen for a period of time, the body accumulates excess nitrogen which can form bubbles in the blood when pressure is reduced. This can result in decompression sickness, also known as "the bends."
