# Test results

Congratulations. You have passed the test and completed the 15 - Pump sizing

Sorry. You did not pass the 15 - Pump sizing test this time Q: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
A: There is no elevation lift and the drawdown has to be added to the suction lift.
01: There is no elevation lift and the drawdown has to be added to the suction lift. Your answer
02: There is no suction lift. Instead there is static water table and the drawdown has to be added to the elevation lift.
03: There is no suction lift and the drawdown has to be deducted from the elevation lift. Q: What are the two factors that should be ensured when the total head for a ground water pump is calculated?

A: The minimum size of the pump Q: Identify which of the following sentences are true:
A: Groundwater typically requires more treatment than surface water.
02: To improve the filtering function, the borehole diameter must be exactly the same as the casing diameter.
03: The drawdown is the difference between the static and the dynamic water level. Q: Identify which of the following sentences are true:
A: To improve the filtering function, the borehole diameter must be exactly the same as the casing diameter.
01: Groundwater typically requires more treatment than surface water.
02: To improve the filtering function, the borehole diameter must be exactly the same as the casing diameter. Your answer
03: The drawdown is the difference between the static and the dynamic water level. Q: Identify which of the following sentences are true:
A: The drawdown is the difference between the static and the dynamic water level. Q: How do we calculate head requirement from the pump?
A: Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
01: Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes Your answer
02: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
03: Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes Q: How do we calculate head requirement from the pump?
A: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes Q: How do we calculate head requirement from the pump?
A: Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes
