An Incompressible Fluid Is Flowing Through a Pipe with a Constriction

question 30

Multiple Choice

An incompressible fluid is flowing through a pipe with a constriction. The pipe is on an incline with an angle of 30.0 degrees. The narrow section is 10.0 m from the wide section and the narrow section is higher than the wide section. The velocity of the fluid in the wide section of the pipe is 4.00 m/s. The diameter of the wide section is 12.00 cm and the diameter of the narrow section is 9.00 cm. The pressure of the fluid in the wide section is 250 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1,000 kg/m³)

• A) 210 kPa
• B) 205 kPa
• C) 195 kPa
• D) 184 kPa
• E) 175 kPa
