The function of diffuser vanes is to _____________ the stirring action and to __________ the flow of fluid into the discharge pipe.

• A. Accelerate, disrupt
• B. Reduce, straighten
• C. Enhance, control
• D. Limit, divert

Answer: (B)

The correct answer emphasizes the role of diffuser vanes in both managing the flow of fluid and improving efficiency within a system. Specifically, diffuser vanes are designed to reduce turbulence in the flow as it approaches the discharge pipe, which helps to create a more streamlined flow pattern. This reduction in turbulence is crucial because it minimizes energy loss due to chaotic fluid motion, thereby enhancing the overall efficiency of the pumping or mixing operation. Additionally, these vanes also serve to straighten the fluid flow as it exits the system. A streamlined flow into the discharge pipe is essential for maintaining proper pressure and ensuring that the fluid moves smoothly through the system. Straightening the flow reduces the likelihood of turbulence that can arise from abrupt changes in direction or velocity. This dual functionality—reducing turbulence and straightening the flow—is what makes diffuser vanes a critical component in various mechanical and fluid systems, ensuring optimal performance and effective control of the fluid dynamics involved.
