Q1: The disintegrating pump in which solid matter is broken up before passing out, is

ANS:A - centrifugal pump

The disintegrating pump in which solid matter is broken up before passing out is typically referred to as a centrifugal pump. Centrifugal pumps are commonly used in wastewater treatment systems and other applications where solids may be present in the fluid being pumped. These pumps use centrifugal force generated by a rotating impeller to impart energy to the fluid, causing it to move radially outward. As the fluid moves through the pump, solid particles are subjected to centrifugal force, which helps disintegrate or break them up into smaller particles before being discharged. While reciprocating pumps and pneumatic ejectors may also be used in certain applications, centrifugal pumps are specifically designed and well-suited for handling fluids containing solid matter due to their ability to effectively disintegrate and pass solids without clogging or damage to the pump. Therefore, the most appropriate option from the ones provided is the centrifugal pump.
