How much liquid water can be produced through condensation in one day

In summary: MannoiaIn summary, Rick Mannoia is seeking technical advice for his desalinization project. He wants to know the amount of liquid water that can be produced through condensation in one day from a 1,000 sq ft pool of heated water covered with a chilled baffle and enclosed in a greenhouse. However, there is not enough information provided to accurately calculate this. The average temperature of the water and baffles, as well as the available power, are needed. The water would be heated from black pipes and the baffle would be cooled with running water. The entire unit, which measures 10 x 100 feet, would be in a compact greenhouse to maximize humidity. Based on rough estimates, with 100kW

I am working on a desalinization project and need technical advice. These are the basics:

If I have a 1,000 sq ft pool of heated water, covered with a chilled baffle, then enclosed in a greenhouse, how much liquid water can I produce through condensation in one day?

Any ideas or feedback would be helpful.

Thanks,

Rick Mannoia

There isn't enough information. Whats the average temperature of the water and the baffles?

Water will run through black pipe and solar heated.
Baffels would be cooled with running water.
This entire unit would be encased in a green house.
I am looking for an IDEA of the amount of liquid possible. Any input or questions would be helpful.
Thanks,

only order of magnitude numbers but: If the energy available is solar energy then you have about 1kW/m^2 (depends where you live)
1000 sqft is about 100sqmetres so about 100kW of available energy.
The latent heat of vaporisation for water is 2.3 x 10^6J/kg and so with 100kW of available energy water would evaporate at a rate of 100kW/2.3x10^6 kg/sec
ie about 0.04kg/sec that is 40 grams per second.which is about 144kg per hour
Obviously your available power will have an impact on this calculation but I hope it helps.

The water would be heated from black pipe, similar to solar water heater for a swimming pool, and the metal baffle would have running chilled water continuing to keep it cool. The entire unit, 10 x 100 feet would be in a compact green house maximizing humidity.

Wouldn’t the fact that the baffle is cooled accelerate condensation?

If this unit were in a very hot environment; Africa, India, how many gallon per day could it produce?

What is condensation?

Condensation is the process by which a gas or vapor turns into a liquid. It occurs when the temperature of a gas or vapor drops below its dew point, causing the molecules to slow down and come together to form liquid droplets.

What factors affect the amount of liquid water produced through condensation in one day?

The amount of liquid water produced through condensation in one day is affected by various factors such as temperature, humidity, air pressure, and the surface area of the condensing surface. Higher temperatures and humidity levels, as well as lower air pressure, can increase the rate of condensation, while a larger surface area can lead to more liquid water being produced.

How can the amount of liquid water produced through condensation in one day be measured?

The amount of liquid water produced through condensation in one day can be measured using a device called a hygrometer. This instrument measures the relative humidity in the air and can calculate the amount of water vapor present. By comparing the humidity levels before and after the condensation process, the amount of liquid water produced can be determined.

Can the amount of liquid water produced through condensation in one day vary in different locations?

Yes, the amount of liquid water produced through condensation in one day can vary in different locations. This is due to differences in temperature, humidity, and air pressure in different regions. Areas with higher temperatures and humidity levels, such as tropical regions, may experience more condensation and therefore produce more liquid water compared to colder and drier regions.

What are some practical applications of understanding the amount of liquid water produced through condensation in one day?

Understanding the amount of liquid water produced through condensation in one day is important in various industries such as agriculture, meteorology, and building construction. It can help farmers determine when to water their crops, aid meteorologists in predicting weather patterns, and assist engineers in designing buildings with proper insulation to prevent condensation and moisture buildup.
