Question

The velocity of the water flowing from the inlet pipe is less than the velocity of water flowing out from the spin pipe B.

• A. variation of water level in vessel will be irregular.
• B. water level will remains constant.
• C. the water level will perform periodic oscillation motions.
• D. none of the above.

Answer 1

The correct option is C the water level will perform periodic oscillation motions.

When the water level increases in the vessel, then pressure will also increase, which will lead to increase in flow rate at pipe B and when again level of water decreases, velocity will also decrease. This will follow a periodic oscillatory motion.
