    pumping storm water in civil and environmental. They are an integral part of engineering and an understanding of how they work is important. Pumps are devices that transfer mechanical energy from a prime mover into fluid energy to produce the flow of liquids. There are two broad classifications of pumps: positive displacement and dynamic. Dynamic Pumps Dynamic pumps add energy to the fluid by the action of rotating blade‚ which increases the velocity of the fluid. Figure 1 shows the construction
