Why in manometer has different height with different fluid
A manometer is a device used to measure pressure in a fluid, typically a gas. It consists of a U-shaped tube filled with a fluid, such as water, mercury, or oil, and a sample of the gas whose pressure is to be measured is applied to one side of the U-tube. The difference in the height of the fluid in the two arms of the tube indicates the pressure of the gas being measured.
The reason why different fluids in a manometer can result in different heights is due to their densities. The height of the fluid in the manometer depends on the balance of forces acting on it, which include the weight of the fluid and the pressure difference between the two arms of the tube.
The pressure difference between the two arms of the U-tube is the same, regardless of the type of fluid used in the manometer. However, the weight of the fluid is proportional to its density, so the height of the fluid column will be different for fluids of different densities, even if the pressure difference remains the same.
For example, if water and mercury are used in a manometer to measure the same pressure, the height of the mercury column will be much shorter than the water column, since mercury is much denser than water. The difference in height reflects the difference in the weight of the two fluids needed to create the same pressure difference.
Therefore, the choice of fluid in a manometer depends on the specific application and the range of pressures being measured, as well as the density andother properties of the fluid being measured.
Pemahaman
Perbedaan ketinggian pada manometer bergantung pada densitas masing-masing fluida. Akan tetapi, hal tersebut dapat terjadi juga karena resultan gaya pada masing-masing bagian tabung(kanan atau kiri).
Berdasarkan manometer, tekanan pada kedua tabung jumlahnya sama, sehingga menghasilkan p1 = p2.
Semakin besar densitas fluida, maka semakin rendah pula ketinggian fluida tersebut dari permukaan tabung manometer
