Step 1
First, we need to determine the velocity of the water flow. We can use the equation Q = A * V, where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the water. Given that the flow rate is 6 l/s, we need to convert it to Show more…

Water at 60°F (v=1.21×10⁻⁵ ft²/s) is to flow from reservoir A to reservoir B through a pipe of length 1700 ft and roughness 0.0005 ft at a rate of Q= 26 ft³/s as shown in Figure 2. The system contains a sharp-edged entrance and four flanged 45° elbow. Determine the pipe diameter. a. 2.1 ft b. 0.6 ft c. 6 ft d. 3.6 ft e. 1.6 ft

Calculate the water flow rate in the system shown in Fig. P8.92. The piping system includes four gate valves, two half-open globe valves, fourteen $90^{\circ}$ regular elbows, and 250 ft of 2 -in. schedule 40 commercial steel pipe (with an actual inside diameter of 2.067 in.). Assume threaded connections and a square-edged pipe entrance.
Figure $14-46$ shows two sections of an old pipe system that runs through a hill, with distances $d_{A}=d_{B}=30 \mathrm{m}$ and $D=110 \mathrm{m} .$ On each side of the hill, the pipe radius is 2.00 $\mathrm{cm} .$ However, the radius of the pipe inside the hill is no longer known. To determine it, hydraulic engineers first establish that water flows through the left and right sections at 2.50 $\mathrm{m} / \mathrm{s}$ . Then they release a dye in the water at point $A$ and find that it takes 88.8 s to reach point $B$ . What is the average radius of the pipe within the hill?
