Water flows into a pipe and out through a double wye. If two of the exits have the same pipe diameter as the entrance, how does the velocity of the third exit compare to that of the entrance?
Answer Choices:
A. Exit velocity is greater than entrance velocity.
B. Exit velocity is less than entrance velocity.
C. Exit velocity is the same.
D. The relationship cannot be determined.

Water flows through the pipe in the figure below and exits to the atmosphere at the right end of section C. The diameter of the pipe is 2.12 cm at A, 4.24 cm at B, and 0.880 cm at C. The gauge pressure in the pipe at the center of section A is 1.25 atm and the flow rate is 0.856 L/s. The vertical pipes are open to the air. Find the level (above the flow midline as shown) of...
Water with pressure of 190 kPa flows down hill through a pipe with a 3.90 cm diameter hose at a speed of 1.2 m/s. It then exits through a smaller pipe m of diameter 1.50 cm which is 5.00 m below the upper pipe. a. What is the speed of the water exiting at the lower pipe opening? b. What is the water pressure at the exit of the lower pipe. ?
Water flows through the pipe in Figure 13-39 and exits to the atmosphere at C. The diameter of the pipe is 2.0 cm at A, 1.0 cm at B, and 0.8 cm at C. The gauge pressure in the pipe at A is 1.22 atm and the flow rate is 0.8 L/s. The vertical pipes are open to the air. Find the level of the liquid-air interfaces in the two ver- tical pipes. Assume lami- nar nonviscous flow 0) FIGURE...
Water flows through a 30° pipe bend at a rate of 200 gpm. The diameter of the entrance to the bend is 2.5 in. and that of the exit is 3 in. The pressure in the pipe is 30 psig, and the pressure drop in the bend is negligible. What is the total force (magnitude and direction) exerted by the fluid on the pipe bend?
Water Flows from reservoir A to a straight pipe through a protrunding pipe entrance, and then enters reservoir B. The velocity head of the pipe flow is 1.6ft. Calculate Minor loss from A to B
9. Water (p=998 kg/m) flows through the 200 mm-diameter pipe at 4 m/s. If it exits into the atmosphere through the nozzle, determine the resultant force (in N) the bolts must develop at the connection AB to hold the nozzle onto the pipe. 200 mm B 100 mm Figure 7
7. Water flows through a pipe of diameter 1.08m at a velocity of 2m/s. If someone puts a nozzle on the end of the pipe, reducing the diameter to 0.35m, at what speed will the water exit the pipe?. 10. A pipe with a radius of 50 cm has water flowing at 5 m/s. If water goes into a new pipe with radius 33 cm, how much will the pressure decrease? 11. A large dam has a hole that is...
Two round pipes have water flowing through them. Pipe B is half
of the diameter of pipe A. If the average velocity of the flow
through both pipes is the same, what is QA/QB?

Problem 1. Water flows from a large tank through a smooth pipe of length 80 m. Both the tank free surface and jet exit are exposed to the atmosphere. Take the density of water p = 1000 kg/m3, dynamic viscosity of water u = 0.001 kg/m.s, atmospheric pressure = 100 kPa, and gravity = 9.8 m/s2. Calculate the volumetric flow rate through the pipe. Neglect entrance losses to the pipe. Hint: Consider the inlet and outlet sections of the pipe...
(b) Water flows under gravity between two reservoirs through a pipe of length 5000m. The diameter of the pipe is 0.2 m and the roughness size is 0.04 mm. The water levels in the two reservoirs are maintained with a difference of 50 m. Determine the discharge through the pipe. Neglect all minor losses. Use the attached Moody diagram for estimation of friction factor. (10 marks) (c) In (b), now include entry loss at the upper reservoir with loss coefficient...
