Water is flowing through the pipe above. The picture shows a side view of the pipe, so points C and D are some distance vertically below points A and B. You can take the density of water to be 1000 kg/m³. Use g = 9.80 m/s².

The cross-sectional area of the pipe is a at point A, 3a at both B and C, and 9a at point D.

Part A: The water speed at point B is 4.80 m/s, and the pressure at point B is 91.0 kPa. Points C and D are a vertical distance of 1.10 m below point B. Calculate the pressure at point C.
_______ kPa

Part B: Calculate the speed of the water at point D.
_______ m/s

Part C: Calculate the pressure at point D.
_______ kPa
