A fluid with viscosity η = 5.2 x 10-3 Pa s is flowing horizontally in the pipe shown below. Section 1, 2, and 3 have radii of r1 = 8 cm, r2 = 6 cm, and r3 = 4 cm, respectively. All section have the same length L = 5.0 m. The speed of the fluid in Section 1 is v1 = 1.49 m/s, and the volume flow rate in Section 2 is F2 = 0.025 m3/s. What is the volume flow rate in Section 1? What is the pressure difference in Section 2 due to the viscosity of the fluid? What is the speed of the fluid in Section 3? What is the pressure difference in Section 3 due to the viscosity of the fluid?

Question

A fluid with viscosity η = 5.2 x 10-3 Pa s is flowing horizontally in the pipe shown below. Section 1, 2, and 3 have radii of r1 = 8 cm, r2 = 6 cm, and r3 = 4 cm, respectively. All section have the same length L = 5.0 m. The speed of the fluid in Section 1 is v1 = 1.49 m/s, and the volume flow rate in Section 2 is F2 = 0.025 m3/s.

What is the volume flow rate in Section 1?

What is the pressure difference in Section 2 due to the viscosity of the fluid?

What is the speed of the fluid in Section 3?
