Question: A 7.7 cm diameter horizontal pipe gradually narrows to 5.5cm. When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 30.5 kPa and 21.2 kPa, respectively.
1- What is the volume rate of flow?
If possible just a brief explanation how you got the answer?
