A horizontal pipe shown in the figure has a cross-sectional area A1 = 37.5cm2 at the wider portions and A2 = 9.40cm2 at the constriction. Water is flowing in the pipe, and the discharge from the pipe is 5.85×10?3m3/s (5.85L/s ).
Part A Find the flow speed at the wide portion.
Part B Find the flow speed at the narrow portion.
Part C Find the pressure difference between these portions.
Part D Find the difference in height between the mercury columns in the U-shaped tube.
