Is high impact polystyrene sustainable?

no because it is made out of oil which is a fossil fuel and there is not much it is running out and if you want it to be sustainable you will have to be like america and invade other countries with oil


Where the transformer oil is circulated in the transformer and how it's cooling the transformer?

Depends on the size of the transformer. Are you are talking about a large power transformer, say 2.5MW or above? If so then the following is usually true. The core/windings of the transformer are immersed in the oil. When the transformer is energised and carrying load the winding heats up. This in turn heats the oil. The tank of the transformer is usually cool due to the air surrounding it. The hot oil moves away from the core to the cooler tank sides. This starts the oil circulating. i.e. as it moves to the side it cools down and then returns to the centre and gets heated up again. As the transformer load increases so does the winding temperature. This means that the oil has to dissipate more heat. Eventually the capacity of the oil to dissipate the heat quickly enough will be reached. If this temperature is reached before the transformer is fully loaded that damage may occur Increasing the size of the tank is one solution However, this could mean a very large piece of equipment. The normal practice is to install a cooling bank or set of "cooling fins". They are also sometimes known as radiators. Generally they are separate from the transformer and connected to it by a flow and return pipe. The flow to pipe is high up near the top of the transformer and the return is near the base. A pump is then used to circulate the oil through them. The pumps are temperature controlled. They only come on when the oil has reached a certain temperature. If this cooling is not sufficient then fans are added. These fans are positioned under the cooling banks. When they are switched one they force air over the cooling banks. This additional air flow takes the heat way faster thus cooling the oil quicker. The pumps then return it to the main tank where it is heated by the core/ windings again.


Why breather is not used in fluid coupling?

Breather is provided where the oil tends to give out fumes after getting heated. in a fluid coupling the fluid is not heated upto that temperature hence not required

What is the difference between high density and low density?

Density, in terms of matters indicate the mass per unit volume, for example oil will be more dense than water. For electronics high density indicates more closely packed with components. For example a high density board will have many more components than a simple circuit board.

What happens to mineral oil when it is heated?

When mineral oil is heated, it expands and becomes less viscous. If the temperature continues to rise, mineral oil can start to decompose and produce vapors that can be flammable. Additionally, prolonged exposure to high temperatures can cause mineral oil to break down and form harmful byproducts.


What is the density of mineral oil?

The density of mineral oil typically ranges from 0.8 to 0.87 grams per cubic centimeter at room temperature.


What is the freezing temperature of mineral oil?

-30C(-22F) is listed as the freezing point for mineral oil. Due to viscosity (how thick the fluid is, basically), however, it's lowest useful temperature is considered to be 10C (50F).


How do you gain the volatile in mineral oil?

To increase the volatility of mineral oil, you can heat it at high temperatures to help the lighter components evaporate. However, this process may alter the properties of the mineral oil and should be done with caution. It's important to note that altering the volatility of mineral oil can affect its performance and intended usage.


What are engine oil temperature ranges?

Normal operating temperature is 212 F ( 100 C) Syntetic oil is good until 260 F, mineral until 240 F


Why does engine oil pressure becomes high?

The pressure will be high until the oil reaches full operating temperature.


How do you make water soluble mineral oil?

Water-soluble mineral oil can be made by emulsifying mineral oil with a suitable emulsifier in water. The emulsifier helps to disperse the oil in water and stabilize the solution. Additionally, using a high-shear mixer can help in achieving a stable water-in-oil emulsion.


What is silicone oil and the difference with mineral oil?

Silicone oil is a synthetic oil made of silicon polymer, while mineral oil is a byproduct of petroleum refining. Silicone oil has a higher resistance to temperature changes and oxidation compared to mineral oil. Additionally, silicone oil is less likely to cause skin irritation and is commonly used in medical devices and personal care products due to its inert properties.


What type of oil works best for a lava lamp in a bottle?

The best type of oil to use in a lava lamp is mineral oil. It has a high boiling point and is clear, so it won't interfere with the lava lamp's coloring. Make sure to use a high-quality mineral oil to prevent any residue buildup in the lamp.
