Test results
Q: Identify the factors that are not considered for calculating the total pump head requirements?
A: Friction losses
Q: Identify the factors that are not considered for calculating the total pump head requirements?
A: Elevation lift
Q: Identify the factors that are not considered for calculating the total pump head requirements?
A: Pump flow
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
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
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.
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 suction lift. Instead there is static water table and the drawdown has to be added to 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: There is no suction lift and the drawdown has to be deducted from the elevation lift.
Q: What determines the minimum flow of a pump?
A: The amount of water that needs to be applied to the crops during peak periods.
Q: What determines the minimum flow of a pump?
A: The type of soil in the field.
Q: What determines the minimum flow of a pump?
A: The cost of power for the pump.
Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 8 hours
Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 12-18 hours
Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 24 hours
Q: Identify which of the following sentences are true:
A: Groundwater typically requires more treatment than surface water.
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.
Q: Identify which of the following sentences are true:
A: The drawdown is the difference between the static and the dynamic water level.
