  • Q2. Principle of steam ejectors.
  • Ans. 

    Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.

    • Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.

    • The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.

    • Steam ejectors are commonly u...
