9) In a section of horizontal pipe with a diameter of 3.0 cm, the pressure is 100 kPa and water is flowing with a speed of 1.5 m/s. The pipe narrows to 2.0 cm in diameter. (a) What is the mass flow rate of the water in the pipe before it narrows? (3 points) (b) What is the speed of the water in the pipe after it narrows? (3 points) (c) What is the pressure in the narrower region? Assume the water is at the same height as when it started. (3 points)
