During the evolution of the world superimposed on the floating islands, the humidity on the floating islands was still high due to the influence of the vapor clouds below.
The high humidity creates good conditions for water condensation magic.
Just use the freezing magic directly on the heat exchanger of the central cooling tower.
The cooling tower heat exchanger is similar to the heat dissipation device of electronic equipment. Two sets of disconnected water pipes pass through a pile of metal sheets, using metal heat conduction to balance the temperature.
The difference is that the complexity of industrial-grade applications is much higher. A set of large fans are deployed in the horizontal direction of the heat exchanger to blow air, and there is a spray system above.
However, due to insufficient heat, the flow rate in the pipeline is limited, and they have only been tested for a short period of time. If they are actually operated, the water temperature will drop too low.
The freezing magic array was quickly produced by the Redstone Magic Equipment Factory and physically connected to the heat exchanger.
The short circulation mode of the cooling tower only goes around the artificial ice forest in the north of the reservoir. The trees in the artificial forest are not mature enough and the area is small. When the water comes out of it, it is still about 20 degrees and flows back to the cooling tower. If the temperature rises by one or two degrees, there is still considerable room for cooling.
Use the freezing spell on the heat exchanger to make some areas drop below ten degrees. Using the huge surface area of the heat exchanger, you can achieve a certain flow rate of water condensation.
According to the environmental conditions of 30 degrees Celsius and 90% humidity, approximately 1,000 tons of condensed water can be obtained per hour.
It sounds like a lot, but it’s still a drop in the bucket for giant reservoirs.
More water still depends on ambient temperature changes.
Based on the exploration team's investigation of the distribution of wind conditions in the reservoir area, an experimental magic array was set up on the inner long-term windward side to create artificial glaciers.
The existing magic is not omnipotent. Most water condensation spells have a very low energy efficiency and are only suitable for bathing and washing hair. If you want to obtain a large amount of water, you still have to rely on freezing magic.
The cooling tower heat exchanger is also connected to the freezing magic, but in order to avoid freezing the water pipes, I dare not use too much power, and it doesn't matter in the wild.
The target of the experimental magic array is also something similar to a heat exchanger, but much smaller, equivalent to the heat sink of an air conditioner outdoor unit with a side length of three meters. The magic array is embedded in the middle of this thing.
After activation, use the three-ring ice sealing technique to cast multiple spells to reduce the temperature of the heat sink without limit.
The cooling effect of magic is quite powerful. Although it is only a third-ring spell, the extreme low temperature can reach minus fifty degrees.
Soon the radiator turned into an ice core and continued to grow outward. From a distance, it looked like a white pimple on the hillside.
The thermal conductivity of ice is very poor, similar to that of bricks. The Freezing Technique is originally a single magic and has no scope of action. Therefore, the range of ice condensation is centered on the heat sink and grows to a radius of tens of meters. , the edge will exceed zero degrees.
In the end, the entire artificial glacier is a water condenser, relying on the magic array inside to maintain itself from melting and continuously condensing water vapor within the range.
Installed together with this ice core water condensation device, there is also the No. 2 experimental device, which is more expensive and has better results.
The core magic arrays of the two are exactly the same, but the supporting equipment is different.
The No. 2 experimental device is composed of a rod and steel strands. A hollow steel pipe is inserted every few meters and connected with strands.
Using the thermal conductivity of steel strands, which is about 35, can slightly improve the heat distribution of the glacier, allowing the glacier to grow larger and thinner.
After the two sets of experimental devices were deployed, someone was watching every day to make flow statistics on the condensed water stream formed below.
The result was not much of a surprise. Device No. 2 won completely due to its huge advantage in the surface area of the ice body.
After the experiment was stopped, the experimental device was dismantled and it was found that the rock mass below the No. 1 device was frozen and cracked. The condition of the No. 2 device was much better. Although the rock mass below had accumulated some stress, it still remained intact.
The next step is to build the No. 2 glacier device in batches.
The goal is to form a glacier of more than ten square kilometers, with a condensation capacity of about 300,000 tons per hour, and it will take four years to fill the reservoir.
It is not impossible to continue to expand, but as the amount of condensed water increases, affected by the water vapor replenishment speed in the reservoir area, the marginal effect decreases and cannot be accelerated too much.
.
To really store water, you still have to count on rain. If it can rain 500 millimeters a day, it won’t last for half a year... Obviously, this amount of rainfall is outrageous enough. The average daily rainfall after the first violent eruption of steam before the plate took off was only 300 millimeters. Many millimeters.
Is it possible to artificially rain?
It seems that you can also try it.
As the worlds stack up, the air pressure and temperature are no lower than they were on the ground, and the rain clouds are still above.
We don't have the ability to mass-produce silver iodide now, and we are not willing to use silver as a consumable. We can only use magic. I just don't know how effective it will be, so let the exploration team give it a try.
At this time, the Redstone Magic Equipment Factory was producing lift devices and freezing magic arrays for aircraft, and it was already at full capacity.
It would be a bit of a waste of scientific research power to hand over such a thing, which only requires a few units, to a scientific research institute. We could simply ask the exploration team to contact the Magic Academy and let the teachers and students do it. They are all magicians themselves, and this saves the step of making equipment.
Moreover, it was a complete transfer, and several Tornado II aircraft were also donated to the Magic Academy.
Two months later, Wang Qi received the report document from the college. As expected, the effect was not good.
Cumulonimbus clouds are too high, and most of the water that falls does not reach the ground and disappears.
This disappearance is not all evaporation. With the current air humidity, the amount of evaporation is only a small amount. A lot of rain will break into fine foam and be blown away by the wind due to the large height difference. This part will be spread over a very large area in the form of drizzle. It may increase rainfall above the reservoir, with half of it spreading to the Fenggu plate.
In short, teachers and students at the college have tried many methods to stimulate cumulonimbus clouds. The best one was because the cumulonimbus clouds pressed down after a temporary decrease in air pressure, bringing about 50 mm of rain to the reservoir area.
It seems that there is no chance of artificial rainfall, but the research has not stopped. Let's just treat it as a project team of the Magic Academy and accumulate some basic knowledge and theories for future weather forecasting.
In addition to slowly advancing several research projects such as agriculture, ghosts, and rainfall, the Magic Academy has some students graduating this year, which is something that all departments are looking forward to.
Wang Qi also got the latest credit statistics.
The total number of students who entered the Magic Academy in the first batch was 2,400. In the second school year, 1,500 students were eliminated. However, some people were dissatisfied and were allowed to attend school at their own expense.
The salary of teachers at the Magic Academy is exaggerated, higher than that of mercenaries of the same level who work hard. According to the tuition coverage salary and experimental loss standards, the per capita tuition is calculated equally among the four grades. The annual tuition is 1,000 yuan. According to A monthly salary of 100 yuan is equivalent to ten months without food and water, which is not something ordinary families can afford. The vast majority of those who are forced to stay are the children of wealthy people who enroll in school through sponsorship.
Even if these people achieve some success in school, they end up serving their own families and have little to do with the kingdom.
Putting aside this part, there are about 500 students of wild mages and ordinary people in the first and second circles, of which 180 are recommended from the Night Clan School and the Sharp Blade School in Phoenix City.
Both Night Tribe and Sharp Blade were creatures transformed by Solaris, with very high mysterious attributes. The two hundred people recommended were also selected. It is not surprising that such a large proportion can be retained.
Graduation is still three months away, and reports of various departments seeking to recruit people have been sent to Wang Qiyu.
