The pressure vapour of methanol at 20 0C is 13,02 kPa.
The water evaporation rate formula is typically calculated using the equation: Evaporation Rate (Area of Water Surface) x (Evaporation Coefficient) x (Difference in Vapor Pressure) / (Thickness of Air Layer).
The evaporation rate equation used to calculate the rate at which a liquid substance transitions into a gaseous state is given by the formula: Rate of evaporation k (Psat - P)
The formula to calculate the evaporation rate of a liquid is: Evaporation Rate (Surface Area x Vapor Pressure x Evaporation Coefficient) / (Molecular Weight x Latent Heat of Vaporization)
The rate of evaporation formula is typically calculated using the equation: Rate of Evaporation (Surface Area of Liquid) x (Rate of Evaporation per unit area). This formula helps determine how quickly a liquid turns into vapor.
The factors that affect the rate of evaporation of alcohol are the exposed surface area of the alcohol, the temperature of the surroundings, and the other particles that are present in the alcohol. The vapor pressure affects the rate of evaporation of alcohol.
Rate of evaporation depends on temperature. As Temp decreases, so does the rate of evaporation.
Maybe I can help you. My experience was with ethanol. It may work with mehanol if it has a distinctive smell like ethanol does. I needed to know how much evaporated off the floor of a room so I could ventilate the room to prevent an explosive condition. I bought a bottle of 100 proof vodka (50% ethanol). I got a stop watch and a graduated cylinder. I carfully measured a specific amount. I found a surface that was the temperature and mass desired to simulate my desired conditions. In my case I used a parking lot surface similar to the highest temperature of the concrete room floor. I pored the ethanol on the parking lot and started my stop watch. Every 10 seconds I put my nose to the wet puddle of ethanol. When I did not smell the ethanol, I stopped the watch. I had my number. There is an equation in some thermodynamics books that uses the vapor pressure, the ambient partial pressure, molecular weight, and temperature to calculate the evaporation rate.
The rate of evaporation increases
Methanol evaporates quickly due to its relatively low boiling point of about 65 degrees Celsius and high vapor pressure at room temperature. Its molecular structure allows for weaker hydrogen bonding compared to water, enabling methanol molecules to escape into the vapor phase more easily. Additionally, methanol's smaller molecular size contributes to its rapid evaporation rate, making it more volatile than many other substances.
The higher the temperature, the higher the rate of evaporation. It is
Heat speeds up the rate of evaporation.
Three factors that affect the rate of evaporation are temperature (higher temperature increases evaporation rate), humidity (lower humidity increases evaporation rate), and surface area (larger surface area increases evaporation rate).
if quality of water reduce the evaporation will decrase
The normal rate of evaporation is dependent on many factors. First, every type of molecule has a different rate of evaporation. For example, acetone has an evaporation rate of 3.0 while water has an evaporation rate of 0.3. You can find a complete listing of each molecule's evaporation rate at your local library. You can also find this information in most laboratories as well.
To calculate the evaporation rate of your swimming pool, you can use a simple formula: Evaporation Rate = (Pool surface area) x (Evaporation rate factor) x (Temperature difference). Measure the surface area of your pool, find the evaporation rate factor for your area, and determine the temperature difference between the pool water and the air. Multiply these values to calculate the evaporation rate.
the rate of evaporation will be equal to the rate of condensation
When air is cooled, the rate of evaporation decreases. Cool air has less capacity to hold moisture, which results in a slower evaporation rate. As the temperature decreases, the relative humidity of the air increases and the rate of evaporation slows down.
