Manometer analog bekerja dengan menggunakan perbedaan ketinggian fluida sebagai indikator perbedaan tekanan. Manometer biasanya berbentuk seperti tabung-U dengan kedua ujung yang terbuka. Apabila terjadi perbedaan tekanan, fluida pada ujung tabung yang memiliki tekanan lebih tinggi akan memiliki tinggi yang lebih pendek, begitu pun sebaliknya. Perubahan tekanan sebanding proporsional dengan perubahan tinggi. Sehingga dapat dihitung perubahan tekanan berdasarkan perubahan tinggi berdasarkan rumus:
ΔP = ρgh
Dengan ρ adalah densitas fluida, g adalah percepatan gravitasi bumi, dan h adalah perbedaan ketinggian yang dialami. Selain itu, tekanan dapat juga didapatkan dengan membaca skala yang terdapat pada tabung-U manometer.
Ada beberapa hal yang mempengaruhi tekanan. Ketinggian mempengaruhi hasil perhitungan tekanan karena pada ketinggian tinggi, tekanan atmosfer berkurang, pun juga sebaliknya. Selain itu, temperatur juga mempengaruhi tekanan, kenaikan pada temperatur sebanding dengan kenaikan pada tekanan. Ada juga kecepatan fluida di lingkungan manometer. Sesuai dengan prinsip Bernoulli, pada aliran fluida tinggi terdapat tekanan yg lebih rendah. Hal ini dapat mempengaruhi pembacaan manometer.
Satuan tekanan pada manometer adalah miliBar, sedangkan satuan SI untuk tekanan ada pascal (Pa).
Pada tanggal 3 Maret 2023, kami belajar mengenai tekanan pada suatu penampang. Tekanan tersebut dapat dihitung dengan:
P = ρ.g.h
dimana ρ adalah densitas fluida, g adalah percepatan gravitasi, dan h adalah kedalaman.

Q: What is a hydrostatic force
A: A hydrostatic force is the pressure exerted by a stationary fluid on a surface that is submerged in it. This force is perpendicular to the surface and is proportional to the density of the fluid, the depth of the surface below the fluid level, and the surface area. The hydrostatic force can be calculated using the formula F = ρghA, where F is the force, ρ is the density of the fluid, g is the acceleration due to gravity, h is the depth of the surface below the fluid level, and A is the surface area. The hydrostatic force plays an important role in a wide range of engineering applications, such as the design of dams, pipelines, and hydraulic systems.
Q: Explain what is buoyancy in fluid mechanics
A: Buoyancy is a force exerted on an object when it is submerged in a fluid, either partially or fully. The force is exerted in an upward direction and is equal to the weight of the fluid displaced by the object. This force is also known as the buoyant force and it can cause an object to float or sink depending on its density relative to the fluid.
According to Archimedes’ principle, the buoyant force on an object is equal to the weight of the fluid displaced by that object. If the object weighs less than the fluid it displaces, the buoyant force will be greater than the object’s weight, causing it to float. Conversely, if the object weighs more than the fluid it displaces, it will sink.
Buoyancy plays an important role in various applications, including ship design, underwater exploration, and the behavior of gases in the atmosphere.
