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

What does ethylene do to the solution in a vehicles radiator?
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.
What are the conditions for reaction between Ethylene oxide and water in a plug flow reactor or in a Continuous Stirred Tank Reactor?
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!!!!!!
How do you use a glycol chiller in my brewery?
Glycol chiller used when beer brewing. This tasked with cooling the propylene glycol. its a food grade anti freeze which require to cool food products.But there are some restriction to use propylene and must to follow the USP grade.Its need chiller system which evolve with compressor, evaporator,condenser and pump. You can read a article from kinnek.com where lot of information available about glycol chiller.
What is GOST 25821-83?
GOST 25821-83 - Fluid PGV EVP Order Number G2017281 ICS Name Other organic chemicals; Hydraulic fluids Aqueous solution of glycerin & polyethylene [ polyoxyethylene ] glycol, improved by additives. Workspace for hydraulic systems.
What should be specification of monoethyleneglycol to be used with water as brine for industrial system?
brine is salt and water usually 100% saturation salt and water freezes at about zero degrees F (non toxic) but rather hard on steel or iron. ethylene-glycol and water at 50/50 mix is about -60 f (very toxic) good with metals propylene glycol and water 50/50 about -40 and a bit toxic good with metal brine is rather cheap salt $30/ton if you live near an ocean and have a bucket real cheap all the others are from big oil and expensive but dont hurt metal water has the highest specific heat of common materials and as such is the best refrigerant
The density of a 20 percent by mass ethylene glycol solution in water is 1.03gml Find the molarity of the solution?
To find the molarity of the solution, you first need to calculate the mass of ethylene glycol in the solution. Then convert it to moles using the molar mass of ethylene glycol. Finally, calculate the molarity by dividing the moles of ethylene glycol by the volume of the solution in liters.
25 percent concentration of ethylene Glycol?
Yes. And the question is ...
When ethylene glycol is added to water the boiling point of water is?
When ethylene glycol is added to water, the boiling point of the resulting solution increases. Ethylene glycol acts as an antifreeze, raising the boiling point and lowering the freezing point of water.
Is ethylene glycol halal?
Ethylene glycol is not of animal origin !
What does ethylene glycol do to the solution?
Raises the boiling point and lowers the freezing point.
Are ethylene oxide and ethylene glycol monomers polymers or neither?
Polyethylene oxide and polyethylene glycol are both known polymers. Ethylene oxide and ethylene glycol are, therefore, monomeric.
How do you make solution of melamine?
Melamine is soluble in ethylene glycol an water at high temperature.
What is the color of ethylene-glycol?
It is clear. If it is at room temperature, and 100% Ethylene glycol is clear.
Is ethylene glycol a polymer?
no, but polyethylene glycol is.
What is the major componet of most major brands of antifreeze?
Ethylene glycol.Ethylene glycol.
Is ethylene glycol and polyethylene glycol the same?
Yes
Ethylene glycol in coolant or propylene gylcol?
Propylene glycol is generally considered safer than ethylene glycol for use in coolant/antifreeze due to its lower toxicity. This makes propylene glycol a preferred choice for applications where accidental ingestion may occur, such as in RVs or marine engines. Additionally, propylene glycol is less harmful to the environment compared to ethylene glycol.
