Hydraulics is a fundamental discipline in engineering with a wide range of applications. It is based on several key principles, including Pascal's Law, hydrostatic pressure, continuity equation, and Bernoulli's principle. Hydraulic systems consist of several key components, including pumps, motors, valves, and cylinders. Hydraulic fluids are used to transmit energy and lubricate components in a hydraulic system. The advantages of hydraulics include high power density, flexibility, and reliability, while the disadvantages include leakage, noise, and maintenance requirements. hydraulic handbook pdf
