Explanation:
An air vessel is used in reciprocating pumps to minimize delivery head fluctuation.
Here's a detailed explanation of each option:
a) Increase the delivery head:
An air vessel does not increase the delivery head of the pump. The delivery head is determined by the pump design and system requirements.
b) Reduce suction head:
The suction head refers to the vertical distance between the pump centerline and the liquid level in the suction tank. The air vessel does not directly reduce the suction head. It is used to reduce the negative pressure or suction fluctuations caused by the reciprocating action of the pump.
c) Minimize delivery head fluctuation:
This is the correct option. An air vessel is primarily used to minimize the fluctuation in the delivery head. The reciprocating action of the pump causes pulsations in the flow rate and pressure. The air vessel acts as a cushion, absorbing the pressure fluctuations and releasing them gradually, resulting in a more stable delivery head.
d) Reduce accelerating head:
The accelerating head refers to the additional head required to accelerate the fluid from rest to the desired velocity. The air vessel does not directly reduce the accelerating head. It primarily focuses on reducing pressure fluctuations.
Summary:
Out of the given options, option 'C' is the correct answer. An air vessel is used in reciprocating pumps to minimize delivery head fluctuation. It acts as a cushion, absorbing pressure fluctuations and releasing them gradually, resulting in a more stable delivery head.
