Select A or B. To increase the head of a water pump, the possible methods are (increasing the diameter of the impeller/increasing the rotational speed of the impeller). The head of a pump depends on its structure (such as the diameter of the impeller, the curvature of the blades, etc.) as well as its rotational speed
Forgot – holding back pressure can also increase head
