Question

Water (ρ = 1000 kg/m³) is flowing vertically in the pipe shown below. The top, middle, and bottom parts have radii of r₁ = 3 cm, r₂ = 1 cm, and r₃ = 3 cm, respectively. The speed of water flow and the gauge pressure at point 1 are v₁ = 20 cm/s and P_{1 gauge} = 200 Pa. The height difference between point 1 and 2, point 2 and 3 is 10 cm. Use g = 10 m/s² for the acceleration due to gravity.

What is the speed of the water flow at point 2?

What is the gauge pressure at point 2?

What is the speed of the water flow at point 3?

What is the gauge pressure at point 3?
