  • Function and Uses of Pumps | Civil Engineering Terms

    2012-3-25 · Function of pumps: Function of the pump is to raise pressure of fluid and impart desirable velocity. So that fluid may be transported from one place to another. More is the velocity the more is the flow rate and hence less time required for transportation. However we know that head loss is directly proportional to the square of flow velocity.
