Question

Which of the following is a direct result of the equation of continuity? Selected Answer: When the open end of a long evacuated tube is inserted into a pool of water, water rises to about 10 m in the tube. The pressure one meter below the surface of water is about 10% greater than atmospheric pressure. The pressure on the inlet side of a horizontal pipe through which water is flowing at constant speed equals the pressure on the outlet side. When the open end of a long evacuated tube is inserted into a pool of water, water rises to about 100 m in the tube Placing your thumb partially over the opening of a hose causes the velocity of the water leaving the hose to increase. None of the above. Response Feedback: Incorrect! Equation of continuity: (area 1) *v1 = (area 2) *v2

Explanation / Answer

Placing your thumb partially over the opening of a hose causes the velocity of water leaving the hose to increase.

This is because when area decreases the velocity increases.
