Problem 3: Water flows through a horizontal cylindrical pipe from a smaller-diameter region to a larger-diameter region. At point A, where the pipe's diameter is 3.5 cm, the water's speed at 25.0 m/s. At point B, the pipe's diameter is 7.0 cm. (a) What is the water's speed at point B? (b) What is the pressure difference between points A and B? Which point has the greater pressure?

Question
Problem 3: Water flows through a horizontal cylindrical pipe from a smaller-diameter region to a
larger-diameter region. At point A, where the pipe's diameter is 3.5 cm, the water's speed at 25.0
m/s. At point B, the pipe's diameter is 7.0 cm.
(a) What is the water's speed at point B?
(b) What is the pressure difference between points A and B? Which point has the greater
pressure?
