Extracted text: Q-2 Water flows through a vertical contraction (venturi) section. Piezometers are attached to the upstream pipe and minimum area section as shown. The velocity in the pipe is 3 m/s. The difference in elevation between the two water levels in the piezometers is 15 cm. What is the velocity at the minimum area? 15 cm 3 m/s
