# Question: What Is Normal Pool Evaporation Rate?

## How do you calculate evaporation rate?

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.

In this case, 5 mL evaporated in an hour: 5 mL/hour..

## How much pool water evaporates daily in Florida?

Pools can lose up to a quarter inch of water per day to evaporation. South Florida is down nearly 10 inches of rain for the year, but it’s not just lawns that are thirsty. Pools need to be refilled regularly to avoid ruining the pump if it starts sucking air.

## What is the evaporation rate?

Safety Data Sheets: An evaporation rate is the rate at which a material will vaporize (evaporate, change from liquid to vapor) compared to the rate of vaporization of a specific known material. This quantity is a ratio, therefore it is unitless.

## Does pool shock kill algae?

Large amounts of algae may require you to add up to three doses of shock over a 36-hour period. When using large amounts of shock to kill algae, water may become cloudy. This should not be a problem, and the water should clear up after running the filter. Wait until the chlorine ppm has fallen below 5.0.

## Can I shock my pool 2 days in a row?

Will the children swim again? Here’s the deal. It’s pretty tough to over-shock your pool; shocking your pool two days in a row with the proper dosage for your pool volume shouldn’t be a problem – and in fact, is sometimes even needed to rid your pool of algae and other contaminants.

## Should I cover my pool every night?

Helps the Swimming Pool Retain Heat For a swimming pool that relies on the sun for heat, covering it at night can still make it warm enough to swim in the next day, instead of losing all the heat overnight when the temperatures drop.

## How much water does a pool lose per day?

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 happens if you put too much shock in your pool?

Although, if you overdo the shock treatment, you risk getting green hair from chlorine due to the excess chlorine oxidizing the copper in the water. You can execute a shock treatment with a few different types of pool shock, just be mindful of how much you’re using.

## How much water can a pool lose due to evaporation?

In fact, the average pool loses 1 ½ inches of pool water a week through evaporation.

## Why does my pool lose water overnight?

If your pool lost water overnight and it is more than the quarter-inch due to evaporation, you probably have a leak. Evaporation accounts for a minor amount of water lost each day. Losing a half-inch or move overnight indicates a problem.

## Where does water go when pool leaks?

The pressurized plumbing system pumps water back to the pool after it has passed through the filter. The filtered water returns to the pool through the jet (or return) inlets. The plumbing that returns the water from the filter to the pool is often referred to as return plumbing.

## How do you calculate the evaporation loss of a swimming pool?

If you divide the distance by the elapsed time, the result will be the rate of water loss (evaporation). To convert this evaporation rate in to gallons lost over a specific time period, you will need convert the measure into a volume.

## Does a pool cover stop evaporation?

It’s the number-one tactic to conserve water. Covers can dramatically slow the pace that water evaporates—particularly on hot days and cold nights. Research shows that covering a pool can slash evaporation by a whopping 95%! Not only are pool covers effective, they offer other benefits.

## Is my pool leaking or evaporating?

If the water went down a similar amount in the pool as well as the bucket, then you lost water due to evaporation. If it went down more in the skimmer and not much at all in the bucket then you have a pool leaking.

## Why does my pool water evaporate so fast?

Lower Your Water Temperature As the temperatures drop, the warm water evaporates even faster. In warm water, molecules turn into mist, which evaporates quickly. This process accelerates when the temperature of the pool water is higher than the air’s temperature. Cold water is more resistant to evaporation.

## How do you reduce pool evaporation?

Here are our top five recommendations:Keep the pool cool. Warm water evaporates more quickly than cool water. … Keep pool accessories simple. … Get a pool cover. … Keep your pets out of the water. … Plug the leaks.

## How much pool water evaporates on a hot day?

Pools that are in direct sun and uncovered for 24 hours a day will lose, on average, a quarter-inch of water during dry, hot weather. This is mainly because heat rises as the air cools. If you do have a pool cover and use it at night, it will hold in the heat and moisture reducing the amount of evaporation water loss.
