(A) Meter (B) Newton (C) Meter of liquid column (D) Joule 3. What has nothing to do with the pump’s head pressure is ( ). (A) Rotational speed (B) Flow rate (C) Pump structure (D) Fluid. Answer: B C D. Head refers to the energy added to a unit weight of liquid by the pump. Denoted by H, it essentially represents the height to which a rotary pump can lift water; it is also known as the total head or overall head. The unit is the height of a liquid column in meters; *metres are commonly used in its place ； In the engineering unit system, the unit of head is commonly expressed in m (meters), that is, it is represented by the height of a column of the liquid being transported in meters. Although the unit of pump head is the same as that of height, the pump head should not be simply understood as the height to which the liquid can be pumped
