Know the secret behind why water tank is round and black in color

Dt. 30 March 2023, Thursday

There was a time when people fetched water from wells every day. After that hand pump came and people used to reach from morning with their bucket or other vessel to fill. After that these types of tanks were made.. in which people used to make cement tanks first. After that now a PVC tank has been made. But one thing common in all these tanks is that these tanks are mostly black in color and secondly they are round. However, now white, blue and green colored tanks are available in the market. And it has stripes on each tank. Do you know why this is so?

Why are tanks round?

Talking about why you have round tanks today, the reason is surprising. The first reason is water pressure. When there is water in the tank, there is pressure on all sides. And if the tank is circular, this pressure is spread evenly on all sides. And another reason is that it is easy to clean. It is also easy to make a round tank. Since this tank is made of PVC, there is no risk of breakage by making it round.

Why is there only a black tank?

Let us tell you that the color of the tank is mostly black. It is not that other color tanks are not available in the market. But the reason behind it is that when the water is left for a long time, it freezes due to heat. As in a lake this kind of green freezes. But since it is a black tank, there is no question of getting green in it. Black color absorbs the most light. In such a case, the black color of the tank absorbs the sun's rays. That is, the sun's rays do not give more influence in black color than other colors of the tank. But the disadvantage of black color against it is that it heats up quickly from the sun's rays. And because of that the water also gets hot. However, colored tanks do not have this type of problem.

Ray of hope for scientists! A rare meteorite found in Gujarat may reveal the secrets of other planets

A meteorite fell in Banaskantha of Gujarat last year in the month of August. This type of astronomical phenomenon was observed after about 170 years. Before this, this kind of astronomical phenomenon was seen in 1852. Scientists stationed in the Space Department of Physical Research Laboratory, Ahmedabad have written extensively about this meteorite. The recent meteorites found in Gujarat can prove to be a very important source for understanding planetary processes. Scientists say that this meteorite is Obrite. They have confirmed that this meteorite may have formed from the rarest heterogeneous material found in our solar system. These meteorites were named Deodar meteorites. It fell on August 17, 2022 in Deodar taluk of Gujarat and is hence named as such. According to reports, the villagers saw no sign of him in the sky, only the sound of thunder.

Ordeal before sending Gaganyaan! ISRO will do a big job on October 21, know the mission objective

Image
Gaganyaan Space: The TV-D1 test flight for Gaganyaan will be launched on October 21 at 7 am from the Satish Dhawan Space Center in Sriharikota. However, after this test, three more test vehicle missions will be conducted. The test involves launching the crew module into outer space and recovering it from the Bay of Bengal after touchdown. This includes testing the Crew Escape System (CIS), which will be used to bring the crew back to Earth if the spacecraft encounters a problem. How important is the mission? This mission of ISRO is very different and special from all the missions till now. So far all the space missions carried out by India have been unmanned. But in this mission, man will be sent from earth to space through space shuttle. After spending seven days there, he will return to earth. This process is very dangerous that is why there are very few countries in the world that have successfully carried out this type of space mission. (Photo-Twitter/ ISRO) The first test w...

84 Earth years are equal to 1 year on this planet, captured by James Webb using infrared wavelengths.

Image
Washington, April 27, 2023, Thursday Some give great importance to the number 84 in the philosophy of life according to the scriptures. There are millions of galaxies and billions of stars in the universe. One of the planets around the solar system is Uranus, the American space agency NASA has shared a picture of Uranus. This image was taken from the James Webb Space Telescope. Uranus is the 7th planet of the solar system orbiting the Sun. When the Voyager 2 spacecraft passed through Uranus Pass in 1986, the camera imaged Uranus as a blue-green round light, but no surrounding ring of light. According to NASA, the image taken by James Webb of Uranus using infrared wavelengths shows that the planet has bright rings around it. A special feature of Uranus compared to other planets in the solar system is that it orbits at a 90 degree tilt on its axis. Hence any season on Uranus is extreme. Here in the polar region the sun is bright for years and then it is dark for as many years. This is...
