What component is primarily responsible for reducing turbulence in fluid pumps?

• A. Impeller
• B. Volute
• C. Diffuser
• D. Casing

Answer: (B)

The volute is primarily responsible for reducing turbulence in fluid pumps. It is a spiral-shaped casing that helps in converting the kinetic energy of the fluid leaving the impeller into pressure energy. By guiding the flow from the impeller smoothly into the outlet, the volute reduces high-velocity jets into lower-velocity streams, which minimizes turbulence and enhances the efficiency of the pump. This design is critical because turbulence can lead to increased energy loss and can cause wear and tear on the pump components. In contrast, while the impeller is responsible for imparting energy to the fluid, it does not specifically address turbulence reduction. The diffuser, found after the impeller in certain pump designs, also aids in reducing velocity and increasing pressure, but the volute is specifically designed to manage the overall flow exiting the pump to prevent turbulence effectively. The casing serves to enclose and contain the components of the pump but does not specifically function to minimize turbulence.
