Chapter 610: The Thermometer That Was Also Pointed Out In Advance, The Loyal Ming Dynasty Navy [Plea
When Yan Changqing, King Zhu Di of Qin, Duke Xin and others, returned to sea after ten days.
Originally, the biogas digester at Yan Changqing was just a digester pit. It was completed after a series of processes such as pit excavation, concrete pouring, and masonry outlet passage.
Of course, not only the biogas digester in Yan Changqing has been completed.
There are also princes Zhu Biao, Zhu Fan, Zhu Di and other princes, as well as the magistrate of Haizhou City and a group of local officials in Haizhou City.
There were also the dean of the old academy and a group of students from the original academy who had attended before. They also supervised and directed the construction craftsmen to build their own biogas digesters within these ten days.
[The First Biogas Tank Academy of the Ming Dynasty], Prince Zhu Biao, Zhu Fan, Zhu Di and other princes, as well as Haizhou City Magistrate, Haizhou City-all local officials and other personnel, as well as the old academy dean, the original academy who were sitting in before of students.
Everyone surrounded Yan Changqing with excitement and anticipation, waiting for Yan Changqing to tell him the next step.
As for Qin King Zhu Fang and Xin Guogong Tang He, they were somewhat uninterested.
The two of them went to sea with Yan Changqing before, and they did not personally direct the construction, so their biogas digester was in the same progress as ten days ago, just digging a pit.
It's not that others are unwilling to help Qin King Zhu Di and Xin Guogong build the methane tank, but if others help them build it, it will lose meaning for them.
After all, if they have not personally supervised and directed the construction of a biogas digester successfully, then how can they say that they have truly learned how to direct the construction of a biogas digester?!!
"Sir, can we put all kinds of livestock and human feces in now?!!"
Prince Zhu Biao asked somewhat uncontrollably.
Yan Changqing shook his head slightly and said:
“Not for now!!!”
"It is better to start a new pond with pure cow and horse manure. Before entering the pond, the cow and horse manure needs to be piled outside the pond for five to seven days in summer. In winter, it can be extended to ten days to enrich the bacteria. , such as quick start.”
"Next, you go prepare pure cow and horse manure and pile them outside the pond."
“Then the currently constructed biogas digesters will be divided into five phases and marked.
"Then we put part of the cow and horse manure that had been soaked for six days into the first phase of the biogas digester."
“Afterwards, a portion of the cow and horse manure that had been soaked for seven days was also placed in the second phase of the biogas digester.
"And so on, until the cow and horse manure that has been soaked for ten days is placed in the fifth phase of the biogas digester."
"In this way, we can later find out the most suitable retting time for cattle and horse manure through comparison at different times."
"In addition, when starting up a new pool, warm water should be used to start it. The water temperature is 30℃-50℃. It is forbidden to use cold water to start up and extend the startup time.
"If you are not sure about the water temperature, this is the thermometer I invented. It has a numerical value on it. If you put the thermometer into the water, you can see the real-time water temperature."
"I have also taught the craftsmen how to make thermometers, and the craftsmen can produce the thermometers you need on their own.
At the end of the conversation, Yan Changqing took out a piece of Wenxi opera and gave it to the princes Zhu Biao, Zhu Di, Zhu Zi and Zhu Di.
Again, after pointing out the technology of glass, many technological items can be found.
For example, a thermometer is also something without much technical content.
The world's earliest thermometer was probably invented in 1593.
The first thermometer in the world at that time was just a glass tube with an open end at one end and a walnut-sized glass bubble at the other end.
When using, heat the glass bubble first, and then insert the glass tube into the water.
As the temperature changes, the water surface in the glass tube will move up and down, and the temperature change and temperature level can be determined based on the amount of movement.
However, the thermometer has the effect of thermal expansion and contraction, so this kind of thermometer is greatly affected by environmental factors such as external atmospheric pressure, so the measurement error is large.
Later, in 1659, the thermometer was further improved, the size of the glass bubble was reduced, and the temperature measuring substance was changed to mercury, thus forming the prototype of the modern thermometer.
Later, in 1714, he observed the boiling temperature of water, the temperature of water and ice when mixed, and the temperature of salt water and ice.
After repeated experiments and approvals, the temperature at which salt water of a certain concentration solidifies is finally set as 0°F, the temperature at which pure water solidifies is set at 32°F, and the temperature at which water boils under standard atmospheric pressure is set at 212°F, represented by ℉ Fahrenheit "This is what became known as the Fahrenheit thermometer.
At the same time that the Fahrenheit thermometer appeared, some people believed that the expansion coefficient of mercury was too small and was not suitable for use as a temperature measurement substance.
Therefore, alcohol was used as the temperature measurement substance, and after repeated practice, it was found that the volume expansion of alcohol containing 1/5 water between the freezing temperature and boiling temperature of water increased from 1000 volume units to 1080 volume unit.
Therefore, the gap between the freezing point and the boiling point was divided into 80 parts, which was designated as the temperature division of the thermometer. This was the later Lieutenant thermometer.
…………Please give me flowers……
More than thirty years after the Fahrenheit thermometer was made, the Fahrenheit thermometer was further improved. The values of the two temperature points were reversed (i.e., boiling point 100 degrees, freezing point 0 degrees), which became the percentage temperature, that is Celsius temperature [expressed in °C.
In Yan Changqing's previous life, Fahrenheit, Lenin, and Celsius were used in various countries around the world.
However, in Yan Changqing's previous life, the motherland mainly used Celsius temperature, so the thermometer invented by Yan Changqing hundreds of years in advance is also a Celsius thermometer.
After arranging for the magistrate of Haizhou City to prepare pure cow and horse manure for retting, Yan Changqing once again took Jin Wang Zhu Fan and Zhu Ji, as well as Xin Guogong Tang He and others to go to sea.
The treatment is still the same as that of Prince Zhu Biao and King of Qin Zhu Di. Let King Zhu Fan of Jin first see the magnificent sight of thousands of ships going to sea and thousands of ships accompanying them.
0
Let Jin King Zhu Fan feel the shock of thousands of artillery fire, and the roar of more than 200,000 soldiers of the Ming Navy:
"The Ming Dynasty Navy is willing to sweep the world and unify all directions for His Majesty the King of Jin!!!"
On the deck, Jin Wang Zhu Fan was so shocked that his heart surged.
On other naval ships below, some naval officers could not help but mutter secretly:
"Which His Highness are we going to conquer and unify all directions for?!!"
"Is it His Highness the Crown Prince?! Or His Highness the King of Qin?!! Or His Highness the King of Jin?!!"
However, this kind of muttering did not last long, and was overheard by the senior navy generals, who then slapped those muttering naval officers on the forehead and said angrily:
“Stop mumbling about that nonsense!!!”
"We are the loyal Ming Dynasty navy, we only want to conquer the world and unify all directions for His Majesty!!!"
"Also, the next time you go to sea, remember to shout, 'Da Ming Navy, I am willing to sweep the world and unify all directions for His Highness King Yan.' Don't shout wrong!!!"
After saying that, he continued to command his ship to follow the [Hongwu] at the front.
And when Jin Wang Zhu Fan's voyage to the sea was over, there was also an inscription on the Spice Islands erected by Jin Wang Zhu Gang.
Similarly, the Ming Dynasty Navy fleet also had an additional copy of the Jin King's decree written by Jin King Zhu Fan on behalf of the Emperor.
