a. what is the speed in the second segment?
b. What is the speed in the third segment?
c. what is the volume flow rate through the pipe?
Solution)
Part a)
A1V1 = A2 V2
π.01^2/4 *9 = π .02^2/4 * v
v = 2.25 m/s
b) A3V3 = A2 V2
π.01^2/4 *9 = π .005^2/4 * v
v = 36 m/s
c)
Q = A1V1 = π.01^2/4 *9 = 0.0007065 L/s (Ans)
======
Good luck!:)

A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.50 cm. Liquid flows through the first segment at a speed of 4.0 m/s. What are the speeds in the second and third segments? What is the volume flow rate through the pipe? If all three parts of the pipe are at the same height and the pressure in the first segment is recorded at 80 kPa, what is the pressure in the second and third segments of the pipe?
K 14.B Problem 14.28 -Enhanced with Feedbaclk A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 5.0 mm. Liquid flows through the first segment at a speed of 9.0 m/s. You may want to review (Pages 373- 378).
Water flows through a horizontal tube of diameter 2.0 cm that is joined to a second horizontal tube of diameter 1.0 cm. The pressure difference between the tubes is 15 kPa. The density of water is 1000 kg/m. Treat the water as an ideal fluid. Find the speed of flow in the first tube. 1.41 m/s 1.73 m/s 2.00 m/s 1.00 m/s
A 7.5-cm-diameter horizontal pipe gradually narrows to 5.0 cm . When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 31.0 kPa and 25.0 kPa , respectively. What is the volume rate of flow? Q= ____ m^3/s Please explain step by step.
