|
How is a pump able to lift water from a well |
By creating a partial vacuum in the pumping chamber |
|
|
How does the diameter of the well affect pumping capacity |
By limiting the size of pump you can install |
|
|
What is the maximum theoretical lift of a centrifugal pump used as a suction pump |
Close to 34 feet |
|
|
Why is a jet pump capable of greater suction lift than a centrifugal pump |
Jet pumps are better at developing negative pressure than a centrifugal pump |
|
|
What is the difference between a shallow well and a deep well |
Depth to the pumping level of the well |
|
|
How does the altitude of a pump installation affect pump selection and installation methods |
Higher elevations do not have as much atmospheric pressure |
|
|
How does friction loss affect the use of a suction pump |
By reducing the amount of work done by atmospheric pressure |
|
|
Why are centrifugal pump suction lines installed with positive grade from the well to the pump inlet |
For better air elimination when priming |
|
|
How may drawdown in a well affect the aquifer |
Drawdown can allow the aquifer to start releasing sand |
|
|
Why should pump capacity be matched to well capacity |
To prevent aquifer problems from developing |
