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: Which of the following options is true about a centrifugal pump?
A: If the pump is pumping at a lower flow, it delivers a higher head.
Q: Which of the following options is true about a centrifugal pump?
A: If the pump is pumping at a lower flow, it delivers a lower head.
Q: Which of the following options is true about a centrifugal pump?
A: If the pump is pumping at a higher flow, it delivers a higher head.
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: 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: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The efficiency of the pump
Q: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The friction loss in the irrigation system
Q: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The minimum size of the pump
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.
