rõhujõul
Rõhujõul is an Estonian term that translates to "pressure force" in English. It refers to the force exerted by a fluid, such as a liquid or gas, on a surface due to the pressure of that fluid. This force is a fundamental concept in physics and engineering, particularly in fluid mechanics. The magnitude of the rõhujõul is determined by the product of the pressure and the area over which the pressure is acting. Mathematically, it is represented by the equation F = P * A, where F is the force, P is the pressure, and A is the area.
Understanding rõhujõul is crucial for analyzing various phenomena. For instance, it explains why a dam needs
