Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
it raises the boiling point and lowers the freezing point
The Feed conditons entering are at 25 deg c with 101.3 kpa the reactor is a cstr operating at 65deg c the product if ethylene glycol!!!!!!
Assume that you have a 25wt% solution of EG. That means you have 25 kg for every 100 kg of solution. Assuming that the EG is dissolved in water means that the solution would contain 25 kg of EG and 75 kg of water. To find the volume % you need to convert each component to a volume by using their densities. The density of water is 1000 kg/m3 and EG is 1113 kg/m3. Using this data we can figure out the volume of each component of solution. For water: 75 kg / (1000 kg/m3) = 0.075 m3 For EG: 25 kg/(1113 kg/m3) = 0.0225 m3 %Vol = 0.0225 m3 / (0.0225 + 0.075 m3) = 0.231 or 23.1% vol
The purpose of a radiator is to transfer heat as quickly as possible. It is pretty much the opposite of an insulator.
They are made from two ingredients, petroleum and natural gas, which are then separated and converted into polymers. Polymers are filled with large molecules called monomers. Monomers are used in a variety of ways to make ethylene. When ethylene is processed it forms a molecular chains that create polyethylene.
Steam radiator valves should always be fully open, or fully closed. Steam enters the radiator from the boiler, and fills the radiator. The air vent shuts, having sensed moisture inside the radiator. The steam then cools, condenses to water, and drains from the radiator. If you leave a valve partially open, then the steam enters easily, because of the pressure. But, the water has a difficult time draining, so the radiator can collect it, and steals it from the furnace, which needs it for resupply.

Raises the boiling point and lowers the freezing point.
Melamine is soluble in ethylene glycol an water at high temperature.

You have a failed radiator. Most vehicles have a trans cooler on the side of the radiator.
The cooling system on these vehicles is drained by detaching the lower radiator hose from the radiator. The radiator doesn't have a drain plug.
Pyrolysis to convert the ethane to ethene. The add Alkaline Pottasium permanganate solution.
NO! That would be dangerous. Cars' coolant systems are pressurized, so if you open the radiator cap while the engine is running, it will spray HOT radiator fluid (water mixed with ethylene glycol, usually) all over you, and sometimes drain the radiator of coolant.
Older vehicles had copper and steel radiators, newer vehicles are made of aluminum and plastic.
It acts as a coolant and prevent the car from overheating during summers. Hope this Helps!!

Basic antifreeze is a solution of ethylene glycol in water. This is not collodial, it's a true solution. However, if other additives are present, it's possible for it to be a colloid.
