Question: A Venturi meter with a 4-in. throat is installed in an 8-in. diameter (vertical) waterline. The pressure difference reading between the throat and entry section

A Venturi meter with a 4-in. throat is installed in an 8-in. diameter (vertical) waterline. The pressure difference reading between the throat and entry section in a mercury-water manometer is 2.01 feet. Determine the flow rate if the flow is moving downward and the distance between the pressure taps is 0.80 feet.
