👉 The term "manometrical" refers to a method used in mechanics and engineering that involves the measurement of forces, moments, or displacements by means of a ruler or other tool. Manometers are commonly used for measuring pressure, temperature, and volume changes due to changes in fluid flow, such as through pipes, tanks, or chambers. The principle is based on the principle of Bernoulli's equation, which states that the sum of forces acting on an object must equal its weight. This
