The evaporation ratio is typically calculated by dividing the enthalpy of steam entering the evaporator by the enthalpy of water entering the evaporator. This ratio helps in determining the amount of steam needed for evaporation.
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 evaporation equation used to calculate the rate of water loss is: Evaporation Rate (Surface Area) x (Evaporation Coefficient) x (Temperature Difference) x (Wind Speed)
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)
Well, honey, the evaporation formula you're looking for is pretty simple: it's just the rate of evaporation equals the surface area of the liquid times the difference in vapor pressure at the surface and in the surrounding air, divided by the resistance to evaporation. So, if you want to know how fast that liquid is turning into a gas, you better get crunching those numbers!
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 conversion from class a pan evaporation to lake evaporation is done by a pan to lake coefficient. The coefficient various from region to region, but is generally from 0.6 to 0.8 and more specifically from 0.7 to 0.75. I would recommend using 0.7 as a ratio. Once you establish the ratio you simply take the class a pan evaporation value and multiply by the ratio. For example, if you have 50 inches of class a pan evaporation then you would use the ratio of 0.7 to estimate 35 inches (0.7*50) of lake evaporation.

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.
No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.
