The total head developed at rated capacity and rated speed for a centrifugal pump is called.

• A. Static Head
• B. Total Rated Head
• C. Suction Head
• D. Total Head

Answer: (B)

In a centrifugal pump, head is the energy the pump adds to the fluid, and the total head is the sum of static head (vertical lift), friction losses in the piping, and velocity head. The pump curve shows how this head varies with flow. The head the pump develops at its rated capacity and rated speed corresponds to a specific point on that curve—the rated operating point. This value is called the Total rated head. It distinguishes from static head, which ignores friction and velocity, and from a generic “total head” since it ties directly to the pump’s rated performance. In practice, engineers use the total rated head to verify the pump can deliver the required system head at the intended flow and speed.
