Centrifugal pump heads: Relationship among static head, suction head, and delivery head.
Assume definitions with negligible pipeline losses for clarity.
Choose the correct relation for the static head.
Difficulty: Easy
Correct Answer: Static head = suction head + delivery head
Explanation:
Definitions
Suction head (H_s): vertical distance between source level and pump centerline (positive if source is below pump).
Delivery head (H_d): vertical distance between pump centerline and delivery level.
Static head: net elevation difference from source free surface to delivery free surface.
Relation Static head = H_s + H_d (ignoring losses).
Final Answer Static head is the sum of suction head and delivery head.
