24 cze 2023 · Figure 9 shows an example of a series of pump curves that represent a turbine pump with multiple impellers. It includes 10 different combinations. This particular pump has two different impeller sizes – a standard size and a “trimmed” or smaller size. The label on each pump curve defines the total number of impellers and the
Figure 1 is a simplified diagram of a typical centrifugal pump that shows the relative locations of the pump suction, impeller, volute, and discharge. The pump casing guides the liquid from
Example 1: If the tank in figure above is filled with water that has a density of 62.4 lbm/ft³ , calculate the pressures at depths of 10, 20, and 30 feet .
In waterworks and wastewater systems, pumps are commonly installed at the source to raise the water level and at intermediate points to boost the water pressure. The components and design of a pumping station are vital to its effectiveness.
Use head-loss vs discharge relationships to calculate flow in pipe networks. Relate normal depth to discharge for uniform flow in open channels. Which forces are in balance in steady pipe flow? How can one combine the effects of pressure and weight? How do we convert between pressure and head?
The first piece of information provided by a pump curve is the flow that the pump will develop at any given operating head. The curve that provides this information is called the pump performance curve.
Guidance is provided for sizing and selection of pumps and pump drives, piping, control valving, flow metering, pump station structures, and operational features.
