What Is Evaporation Rate?

What is evaporation with example?

Evaporation is defined as the process of a liquid changing into a gas.

An example of evaporation is water turning into steam..

What is normal pool evaporation rate?

Normally pools see ¼ – ½ inch loss of water per day due to evaporation. This is roughly 2 – 4 inches per week. For a normal sized pool you will loose 25,000 to 50,000 gallons of water per year due to evaporation.

What are 2 examples of evaporation?

13 Everyday Life Examples of EvaporationDrying Clothes under The Sun. One of the most common real-life examples of evaporation is drying of clothes under the sun. … Ironing of Clothes. … Cooling Down of Hot Tea and Other Hot Liquids. … Wet Floors. … Melting of Ice Cubes. … Preparation of Common Salt. … Evaporation of Nail Paint Remover. … Drying of Wet Hair.More items…

Should I cover my pool every night?

Helps the Swimming Pool Retain Heat Covering a heated swimming pool at night will reduce heat loss. … You don’t have to buy the most expensive pool cover to notice a difference: lower-cost vinyl and solar covers will still keep the water warm.

How is evaporation rate calculated?

Subtract the new cylinder reading from the original reading. This reflects the volume of liquid that has evaporated. For example, 500 mL – 495 mL = 5 mL. Divide the volume of liquid that evaporated by the amount of time it took to evaporate.

Does temperature affect evaporation rate?

Evaporation rates are higher at higher temperatures because as temperature increases, the amount of energy necessary for evaporation decreases. … Humidity, or water vapor content of the air, also has an effect on evaporation. The lower the relative humidity, the drier the air, and the higher the evaporation rate.

What is evaporation in simple words?

Evaporation is defined as the process of a liquid changing into a gas. An example of evaporation is water turning into steam.

Why is the water level in my pool dropping?

No matter which season you are in, your pool can lose inches of water a week. Natural causes such as wind, heat and humidity can contribute to pool water loss. This is a big deal, because if your water level gets too low it may cause your pool pump to suck air and run dry, which can damage it.

What decreases the rate of evaporation?

When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.

What does not affect the rate of evaporation?

Evaporation is a process in which some molecules of a liquid, which have greater kinetic energy, escape from the liquid and enter the atmosphere. … At higher temperature, molecules have greater kinetic energy, hence can easily escape the liquid. But shape of the surface of the liquid doesn’t affect evaporation.

What is the evaporation rate of water?

Evaporation rates, which are provided by meteorological stations, are found by measuring and recording water losses by evaporation over many years. Evaporation rates are usually expressed as the water depth lost in millimetres over a period of time, e.g., 2 mm/day, 14 mm/week or 60 mm/month.

What does the rate of evaporation depend on?

The rate of evaporation depends on surface area, temperature, humidity and speed of the wind. It increases with increase in surface area, temperature, and wind speed.

What is evaporation explain?

Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour.

How much water does a pool lose per week?

A residential pool without a pool cover will lose about 1/4 inch of water level per day or about 2 inches per week solely due to evaporation. This can amount to between 10,000 and 20,000 gallons of water loss per year, depending on the size of the pool and the factors that increase or decrease evaporation.

What increases the rate of evaporation?

The rate of evaporation is affected by the following factors: Temperature: The rate of evaporation increases with an increase in temperature. Surface area: The rate of evaporation increases with an increase in surface area. Humidity: The amount of water vapour present in the air is called humidity.
