What is the science that studies the conveyance of liquids through pipes?

• A. Hydraulics
• B. Hydraulics actuator
• C. Hydraulic Circuit
• D. Rotary Switch

Answer: (A)

Hydraulics focuses on how liquids behave under pressure and move through confined passages like pipes. It covers how fluid pressure is transmitted, how flow is produced and controlled by pumps, valves, and the geometry of pipes, and how factors like pipe size, roughness, and elevation affect conveyance. This makes hydraulics the field that directly studies the conveyance of liquids through pipes. A hydraulic actuator is a device that converts hydraulic energy into motion; a hydraulic circuit is the network of components arranged to perform a task; a rotary switch is an electrical component used to route circuits. So hydraulics is the best answer because it directly deals with moving liquids through piping and the systems that transport them.
