An Incompressible Fluid Is Flowing Through a Pipe with a Constriction

question 41

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 from the horizontal. 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 and the velocity of the fluid in the narrow section of pipe is 9.00 m/s. 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) 169 kPa
• B) 175 kPa
• C) 180 kPa
• D) 193 kPa
• E) 205 kPa
