Swimming Pool Evaporation Rate Calculator


Swimming Pool Evaporation Rate Calculator. Welcome to microwell swimming pool humidity and evaporation extraction calculator. Let’s talk about why this happens, how to calculate the amount of water you lose through evaporation, and how to prevent it.

There’s a large range regarding how quickly pool water evaporates—it can be as little as two millimeters to as much as two inches per week. Of course, while a heavy rain, the level in the tank will rise very high, in the ratio of the areas pool/tank. This will give you the value for the number of gallons of water that you lost.

Most Indoor Pools Are Above 80° F So 20% More Latent Must Be Added To The Listed Values In Most Design Books.


The calculation of evaporation is also required for many other applications and situations. Q = heat supplied (kj/s (kw)) h we = evaporation heat of water (kj/kg) 1 kw = 3412 btu/h; If you had 100 people, this would give you 19,000 btu/h of moisture.

That’s Up To A 1/4″ Of Water Per Day!


The calculation of evaporation is required from a variey of water pools including swimming pools, water storage tanks and vessels, spent fuel pools in nuclear power plants, etc. Evaporation in the swimming pools in normal activity in kg/h m2. Accurate calculation of evaporation from swimming pools is needed to ensure proper sizing of hvac equipment as well as for the estimation of energy consumption.

In This Paper, In Addition To The Author’s Published Correlations For Indoor Swimming Pools, Formulas And Methods Are Also Provided For The Calculation Of Evaporation For The Following:


Of course, the amount varies based on many factors like climatic conditions and pool size. Using the marker, draw a line on the inside of the bucket to mark how much water is inside the bucket. ‘a’ stand for pool water surface area in a square meter.

The Evaporation Estimator Provides The Estimated Evaporation Rate From These Variables For A Particular Pool On A Particular.


W’ is the evaporation rate in kg/hr or liter/hour. We send occasional emails relevant to the swimming pool leak detection industry. If you are looking for complicated:

Usually, Pools Lose Water At Specific Rates Depending On The Weather Conditions And Pool Chemicals.


Pool evaporation is effected by a variety of weather and pool related variables. 0.0291 lb per hour per square foot. P a = water's vapor pressure (mmhg) at dew point temperature.
