How Does The Fan Work?

The Fan is an electronic device that everybody use it in their house. People use the fan to make the air in the room cooler, especially in hot day. And how does the fan work?

(Kipas angin adalah sebuah perangkat elektronik yang orang gunakan di rumah mereka. Orang menggunakan kipas angin untuk membuat udara di dalam ruangan menjadi dingin, khususnya di hari yang panas. Dan bagaimana kipas angin bekerja?)

An electric fan is an electric motor with some fan blades attached to its rotating shaft. As the motor spins, the fan blades rotate. Each blade is angled a bit, and as the inclined plane of the blade moves through the air, it forces the air ahead of it forward. Each blade does this on a continuous basis, and the result is a moving air stream. The fan is taking air from the area behind itself and blowing it out the front.

(Sebuah kipas angin listrik adalah sebuah motor listrik dengan beberapa bilah kipas yang melekat pada poros yang berputar. Ketika poros tersebut berputar, bilah kipas juga akan berputar. Setiap kipas dimiringkan sedikit, dan karena bidang miring pada kipas tersebut bergerak melalui udara, kipas tersebut memaksa udara keluar dari depan. Setiap kipas melakukan hal tersebut secara terus menerus, dan hasilnya adalah aliran udara yang bergerak. Kipas tersebut mengambil udara dari wilayah dibelakangnya dan meniupnya keluar di depan.)

The fan generates a movement of air, causing the warm dense air to descend, and the cool dense air to rise, thus creating a feeling of coolness in the air.

(Kipas menghasilkan gerakan di udara, menyebabkan ketebalan udara panas menurun dan ketebalan udara dingin meningkat, sehingga menyebabkan kesejukan di udara.) 

Making Paper from Woodchips

General statement
Woodchipping is a process used to obtain pulp and paper products from forest trees. The woodchipping process begins when the trees are cut down in a selected area of the forest called a coupe.

Squence of explanation
Next the tops and branches of the trees are cut out and then the logs are taken to the mill. At the mill the bark of the logs is removed and the logs are taken to a chipper which cuts them into small pieces called woodchips. The woodchips are then screened to remove dirt and other impurities. At this stage they are either exported in this form or changed into pulp by chemicals and heat. The pulp is then bleached and the water content is removed.

Closing
Finally the pulp is rolled out to make paper.
