What is the dynamic suction head for a pump that has:

- Static suction head = 8 m
- Suction pressure head = 12 m
- Suction friction head = 2 m
- Suction velocity head = 3 m

A. 5 m
B. 7 m
C. 10 m
D. 13 m

Answer :

Final answer:

The dynamic suction head is not measurable based on the given information.

Explanation:

The dynamic suction head is calculated by subtracting the static suction head, the suction pressure head, the suction friction head, and the suction velocity head from each other.

Dynamic suction head = Static suction head - Suction pressure head - Suction friction head - Suction velocity head

Dynamic suction head = 8m - 12m - 2m - 3m

Dynamic suction head = -9m

Since the dynamic suction head cannot be negative, it is not possible to calculate a valid value. Therefore, none of the given options (A, B, C, D) is the correct answer.
