Water flows through a 600 mm diameter pipe with a velocity of 2.7 m/s. Bulk modulus of water is 2060 MPa and the pipe has modulus of elasticity of 200 GPa. The pipe has thickness of 18 mm. If a valve is closed in 4.5 seconds at the downstream end of the 3200 m. pipeline, what is the peak pressure development by the closure?

A 6-inch-diameter pipeline has a length of 845 ft and flows between two reservoirs with an elevation drop of 33.5 ft. The pipe is ductile iron and the fluid is water at 40° F. Minor losses are listed below. Description Number 90° Bends 9 45° Bends 8 Other R/d=2.5 R/d=5 Gate Valves 4 Fully Open Swing-Check Valves 2 Entrance 1 Square Edge Exit a. Determine the flow rate using the Darcy-Weisbach equation and the fully rough friction factor from the Moody Diagram. Neglect minor losses for this flow estimate. b. Modify the friction factor using the Reynolds number from the flow above. Include minor losses using K values from the class handout. Recompute the flow rate. c. Using the friction factor from (a), convert the minor losses to an equivalent pipe length and use the Swamee-Jain equation for Q to estimate the flow rate. d. Convert the minor losses to an equivalent pipe length for the Hazen-Williams equation. Use a C = 140 and calculate the flow rate by adding the minor loss equivalent…

While planning a future expansion, a water distribution pipe will be replaced as shown in Figure 2. The current plan is for the new configuration to have the same head-loss between points A and B once the new pipes are laid. Considering that the physical characteristics of these new pipes will be identical to the previously laid pipe (L, D, CHW), (A) what will the new operational flow be? After years of wear and tear while operating above the required flow, the pipes have prematurely degraded. The Hazen-Williams coefficients have dropped to: CHW₁= 130, CHW2= 135, CHW3= 125. You must now (B) quantify the head-loss between points A and B for an operational flow of 200 l/s.

DIFFERENT QUESTION FOR REVISON-EXAMINATION   Additional Questions:   (1) A fluid of constant density flows at the rate of 15 Liters/ sec along a pipe AB of 100 mm diameter. This pipe branches at B into two pipes, BC and BD each of 25mm diameter and a third pipe BE of 50mm diameter. The flow rates are such that the flow through BC is three times the flow rate through BE and the velocity through BD is 4 m/s. Find the flow rates in the three branches BC, BD and BE and the velocities in pipes AB, BC and BE. Water is flowing through a pipe with a velocity of 7.2 m/s. Express this velocity as velocity head in meters of water. What is the corresponding pressure in kN/m2. (2) A pipe of 150mm bore is delivering water at a rate of 7500dm3/min at a pressure of 820 kN/m2.It connects by a gradually expanding pipe to a main of 300 mm bore which runs 3 m above it. The main is designed to withstand a maximum pressure of 814 kN/m2. Neglecting loses due to friction determine if the main will fail or…
