A 6.2 cm diameter pipe gradually narrows to 4.0 cm. When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 30.0 kPa and 24.0 kPa, respectively. What is the volume rate of flow?
I think quastion shoud be rong because when the area will decrease due to cross section the pressure shoud increase not a decrease. can you got my point
