Question

An incompressible fluid is flowing through a pipe with a constriction. The pipe is on an incline with an angle of 27.0 degrees. The narrow section is 11.0 m from the wide section and the narrow section is lower than the wide section. The velocity of the fluid in the wide section of the pipe is 2.57 m/s and the velocity of the fluid in the narrow section of pipe is 9.25 m/s. The pressure of the fluid in the wide section is 285 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1,000 kg/m³ .)

Explanation / Answer

Try to use this formula format. Use your knowledge. Section 1 v1 = 4m/s; p1 = 250kPa Section 2 v2 = 9m/s Bernoulli p1/k + v1^2/2g = p2/k + v2^2/2g where k is specific weigh p2 =p1 + k (v1^2 - v2^2) / 2g p2 = p1 + dens (v1^2 - v2^2) / 2 p2 = 250,000Pa + 1000kg/m^3 (16 - 81)m^2/s^2 / 2 p2 = 217.5 kPa -- answer --
