The sudden stoppage in the flow of water in a close conduit results in a phenomena called

(A) Cavitation (B) Hydraulic Gradient
(C) Stack Pressure (D) Water Hammer

Answer: (D) Water Hammer

o Cavitation: Air bubble formation in liquid.
o Hydraulic Gradient: a line joining the points of highest elevation of water in a series of vertical open pipes rising from a pipeline in which water flows under pressure.
o Stack Pressure: It is due to difference in temperature of air at two different layers causing air movement.
o Water Hammer: sudden stoppage in the flow of water in a close conduit.
