For a given centrifugal pumpa)head varies inversely as square of speed...
Explanation:
Centrifugal pumps are widely used to transfer liquids from one place to another. The relationship between the head, discharge, power, and speed of a centrifugal pump is important to understand in order to optimize its performance.
Head:
The head is the height to which a pump can raise water or other fluid. It is measured in meters or feet. The head varies inversely as the square of the speed. This means that if the speed of the pump is doubled, the head will be reduced to one-fourth of its original value.
Discharge:
The discharge is the amount of fluid that a pump can deliver in a given time. It is measured in cubic meters per hour or gallons per minute. The discharge varies directly as the speed of the pump. This means that if the speed of the pump is doubled, the discharge will also be doubled.
Power:
The power is the amount of energy that a pump consumes to transfer a fluid from one place to another. It is measured in watts or horsepower. The power varies directly as the cube of the speed of the pump. This means that if the speed of the pump is doubled, the power will be increased by a factor of eight.
In conclusion, the discharge varies directly as the speed of the centrifugal pump. Thus, option 'B' is the correct answer.
