Question
As shown in the figure, water flows with a velocity v at a depth y in a channel of rectangular section which is closed by a sluice gate. The water floes smoothly down to a vertical shift. Calculate the rise of water level deltay just upstream of the sluice gate. A two dimensional diversion structure diverts the flow downward through a vertical slot with 1 ft opening with the aid of a sluice gate as shown in the figure. By the energy equation. By the momentum equation. Wich one is the correct answer? Why?Explanation / Answer
The water is flow in downward direction with the velocity, during flow of water in downward conditions the gravity is act as a major role.
The water have a Kinectic energy during flow, so it solve by energy equcation
K = 1/2 m v2
m = Mass of the object
v =Velocity of the water
