6. In a process plant, ethylene glycol is transported in a 2-mdiameter piping. To measure the flow rate, a vertically mounted venturi section as shown in the figure is used.

Assume the flow is inviscid and incompressible. Two pressure gages are mounted 10-m apart. Determine the flow rate if the pressure in each gage reads50kPa (hint: Watch video "Chapter 3-vertical venture.mp4")
