1) A 7.6 cm diameter horizontal pipe gradually narrows to 4.8 cm . When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 35.0 kPa and 22.0 kPa , respectively. What is the volume rate of flow? 2)The maximum gauge pressure in a hydraulic lift is 18.2 atm. What is the largest size vehicle (kg) it can lift if the diameter of the output line is 28.3 cm? I've been looking at examples but i keep getting the wrong answer plz help :/
