A circular pipe has a diameter of 3 cm and then narrows to 2 cm. When water (density= 1000 kg/m^3) flows during at a certain rate, the pressure is 32.0 kPa in the larger section, and 24.0 kPa in the smaller section. There is no change in height.
1) What is the speed of water in each section?
2) What is the volume flow rate?
