The three basic parts of any eductor are the nozzle, the suction chamber, and the __________.

Correct Answer: Option B — diffuser

Eductors operate on the Venturi principle. The three essential components are the nozzle, which accelerates the motive fluid; the suction chamber, where the low-pressure area is created; and the diffuser, which converts the high-velocity kinetic energy back into pressure energy to discharge the fluid against a higher back pressure.
