Consider a small rectangular fluid element with the lengths of the edges assumed to be taken from any arbitrary location within the fluid mass of ...
静止流体中的压力变化
静止流体中的压力变化
Consider a small fluid element at rest. The fluid acceleration is zero, and the general equation of motion simplifies accordingly. Under these conditions, ...
流体压力的测量
流体压力的测量
Fluid pressure is measured using liquid columns in tubes, either vertically or at an inclination, termed manometers. The height of the liquid column ...
平面上的静水压力
平面上的静水压力
Consider plane surfaces submerged in a fluid with a specific weight. Forces are developed on the surfaces because of the fluid. The resultant of the ...
曲面上的静水压力
曲面上的静水压力
Consider a swimming pool with a fluid of a known specific weight having a curved surface at the bottom. If the volume around the curved surface is ...
水下和漂浮体的浮力和稳定性
水下和漂浮体的浮力和稳定性
When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body, called the buoyant force. This force acts through ...
