How does fluid pass through a plug cock?

• A. A valve
• B. Rotating the cock
• C. Rotating the plug 180 degrees
• D. Rotating the plug between 0 and 90 degrees

Answer: (D)

Fluid passes through a plug cock by rotating the plug between 0 and 90 degrees. In a plug cock, the element that controls the flow of fluid is a cylindrical plug with a hole through it. When the plug is in the closed position, the hole is perpendicular to the flow path, effectively blocking fluid from passing. By turning the plug from the closed position (0 degrees) to an open position (90 degrees), the hole aligns with the flow path of the fluid, allowing it to pass through unobstructed. This rotational movement is essential for the operation of the plug cock, as it transforms the flow from blocked to open. The distinction of rotating the plug specifically between these angles is important because it ensures that the plug is fully aligned with the flow direction, providing efficient fluid passage when open while maintaining a tight seal when closed. This functionality makes the plug cock a reliable choice for controlling fluid flow in various applications.
