What is a Barometer, Aneroid Barometer and Mercury Barometer working principle II Sailor 360

There are Two types of Barometer II Aneroid Barometer and Mercury Hello Navigator ! Today our topic- What is a Barometer, Aneroid Barometer and Mercury Barometer working principle II Sailor 360 Construction of aneroid barometer: The above diagram shows the main parts of the aneroid barometer. • It has a metallic box B that is partially evacuated. • The top D is kind of springy and is corrugated in the form of a diaphragm. • A thin rod L is placed in the middle of the diaphragm that is toothed at the upper end. • A wheel is placed near to the diaphragm; the teeth of the diaphragm are correctly fitted into the teeth of the wheel. • A pointer P is made to slide with the circular scale. • The circular scale is calibrated with the barometer to read the atmospheric pressure. Additional information: Working of the aneroid barometer: • The diaphragm D gets pressed, when the pressure of the atmosphere increases. Rod L will get depressed. When this happens the wheel S rotates in the clockwise direction and the point P will move to the right of the circular scale. • The diaphragm D will get bulged when the rod L gets moved up and the wheel will be rotating in the anticlockwise side. Due to this the pointer will move to the right. This happens when the atmospheric pressure decreases. Note: • It is important to remember about the types of the barometers. One is a mercury barometer, and another one is an aneroid barometer. • In an aneroid barometer, the pressure will be measured by the metal expansion and in the mercury barometer the mercury’s height must be adjusted to measure the pressure. • Mercury barometer has a simple mechanism, and it is relatively accurate whereas an aneroid barometer needs a complex mechanism. ---------------------------------------------------------------- Video Sections: 0:00 - Introduction 0:05 - Explanation -------------------------------------------------------------------------------- For Sponsorship Contact us at: ashif.luckey@gmail.com --------------------------------------------------------------------------------- Website : https://sailor360.net ------------------------------------------------------------------------------------------ Thank you for watching this video.See you in next video. #sailor360
