Q: A small quantity of water may be lifted to a great height by
  • A. Hydraulic jack
  • B. Hydraulic coupling
  • C. Hydraulic ram
  • D. Hydraulic lift
Correct Answer: Option C - Hydraulic Ram–It is an automatic device which does not require any external power as its automatic action is due to the inertia forces of water itself. With the help of a ram a large quantity of water available at a smaller head is utilized for lifting a small quantity of water to a greater height. It works on the principle of water hammer, moving mass of water suddenly stopped. Hydraulic lift:-Elevator operated by fluid pressure • Generally used in garages or service centers to raise automobiles. • Works on the principle of Pascal's law.
