An Incompressible Fluid Is Flowing Through a Vertical Pipe with a Constriction

question 28

Multiple Choice

An incompressible fluid is flowing through a vertical pipe with a constriction. The wide section is 2.00 cm in diameter and is at the top of the pipe. The pressure of the fluid in the wide section at the top is 200 kPa. The velocity of the fluid in the wide section is 4.00 m/s. The narrow section is 1.00 cm in diameter and is located 2.00 m below the wide section. What is the pressure of the fluid in the narrow section? (density of the fluid is 1,000 kg/m³)

• A) 72.0 kPa
• B) 80.0 kPa
• C) 99.6 kPa
• D) 105 kPa
• E) 116 kPa
