Question

Consider a venturi with a small hole drilled in the side of the throat. This hole is connected via a tube to a closed reservoir. The purpose of the venturi is to create a vacuum in the reservoir when the venturi is placed in an airstream. (The vacuum is defined as the pressure difference below the outside ambient pressure.) The venturi has a throat-to-inlet area ratio of 0.85. Calculate the maximum vacuum obtainable in the reservoir when the venturi is placed in an airstream of 82 m/s at standard sea level conditions. (Note: The standard sea level density is 1.23 kg/m3. Round the final answer to the nearest whole number.) The maximum vacuum obtainable in the reservoir is N/m2
