What is the expansion ratio of lpg gas?
Of course it depends on the target pressure and temperature, so I don't have an exact answer, but I can show you how to make a good guess can form the density of liquid propane and the ideal gas law. The density of the liquid material at average sea-level atmospheric pressure and at its boiling temperature I have looked up and found to be 582 kg/m3. The gas at 25 C and average sea-level atmospheric pressure has a density of (moles*Molecular weight)/Volume = (Pressure*molecular weight)/(ideal gas constant*absolute temperature). Pressure = 1 atmosphere Molecular weight = 0.0441 kg/mole Ideal gas constant = [0.00008206 M3 Atm / K] Absolute temperature = 298.15 (i.e., 25 C) or density = 1 Atm * 0.0441 kg/mole / (0.00008206 M3 Atm /K * 298.15 K) = 1.8025 Kg/M3 Literature seems to say 1.8324 Kg/M3 (which is the same as g/L). This is simply because the ideal gas law is only an approximation -- this gas is close to it liquefaction point, so it is showing some discrepancy from ideal behavior. The expansion Ratio to get to standard conditions is therefore close to 582/1.80, or ~320
What is weight of 100 octane aviation gasoline?

How much does Portland cement dry powder weight?
The weight of Portland cement dry powder typically ranges from about 94 to 100 pounds per cubic foot, depending on the specific type and brand. In standard packaging, a bag of Portland cement usually weighs 94 pounds (approximately 42.6 kilograms). This weight can vary slightly based on moisture content and compaction during storage.
What is the density of foamed nitrile rubber?
Dividing weight by volume . W/v - kg/m3.
What is uniformity coefficient?
The measure of variation in particle sizes of filter and ion exchange media. The coefficient is defined as the the ratio of the sieve size that will permit passage of 60% of the media by weight to the sieve sieve size that will permit passage of 10% of the media material by weight.
What is the cost of ultra-high molecular weight polyethylene?
rate of uhmwpe made by reliance is around Rs. 106/= per kg. rate of uhmwpe made in china(ISO (9001) is around Rs. 155/- per kg.
What is the chmical name of th hmldpe?
The chemical name for high-molecular-weight polyethylene is polyethylene. It is often referred to as HMW-HDPE (high molecular weight high density polyethylene).
What is the average molecular weight of polytetrafluoroethylene or Teflon?
The average molecular weight of polytetrafluoroethylene (Teflon) is approximately 100,000 to 1,000,000 g/mol.
What are the differences between polyethylene oxide and polyethylene glycol?
Polyethylene oxide and polyethylene glycol are both polymers made of repeating ethylene glycol units. The main difference between them is their molecular weight. Polyethylene oxide has a lower molecular weight and is a liquid at room temperature, while polyethylene glycol has a higher molecular weight and is a solid or semi-solid at room temperature. Additionally, polyethylene glycol is commonly used in pharmaceuticals and cosmetics, while polyethylene oxide is used in industrial applications.
What is the cost of ultra high molecular weight polyethylene?
200 rs./kg
What is the average molecular weight of polyethylene?
The average molecular weight of polyethylene can vary significantly depending on its type and method of production, typically ranging from about 5,000 to over 1,000,000 g/mol. Common grades of low-density polyethylene (LDPE) have molecular weights around 20,000 to 300,000 g/mol, while high-density polyethylene (HDPE) often falls between 100,000 and 1,000,000 g/mol. The molecular weight influences properties such as strength, flexibility, and processing characteristics.
What is the density of HMHDPE?
The density of high molecular weight high density polyethylene (HMHDPE) typically ranges from 0.945 to 0.965 grams per cubic centimeter.
Is UHMW a thermoset plastic?
UHMW stands for Ultra High Molecular Weight. Now it depends what the monomer is. UHMWPE would be thermoplastic not thermoset. But other UHMW polymers can be thermoset. It depends.

How do you calculate number average molecular weight given molecular weight range and fraction?
To calculate the number average molecular weight, multiply each molecular weight value within the range by its corresponding fraction, then sum up these products. This sum represents the numerator of the equation. Next, sum up all the fractions in the denominator. Finally, divide the numerator by the denominator to obtain the number average molecular weight.
What has the author Bart D Colenbrander written?
Bart D. Colenbrander has written: 'Ultrasonic welding of roll-drawn high molecular weight polyethylene tapes'
Is polyethylene soluble What is it's solubility in g100ml Why?
Polyethylene is insoluble in most solvents due to its high molecular weight and non-polar nature. Its solubility in water is very low, typically less than 0.01 g/100mL, making it practically insoluble in water.
