A pipeline of 50 mm diameter and 4.5 km length connects two reservoirs whose constant difference of water level is 12 m. A branch pipe 1.25 km long and taken from a point distance of 1.5 km from reservoir A, leads to reservoir C whose water level is 15 m below that of reservoir A. Find the diameter of the branch pipe so that the flow into both the reservoirs is the same. Assume the coefficient of friction for each pipe, f = 0.0075, and neglect minor losses.

Problem 10.1 Water flows steadily through a 180° reducing pipe bend as shown in the figure (notice the transition from a larger diameter at section 1 to a smaller diameter at section 2). The atmospheric pressure outside the piping system is Patm = 100 kPa. The pipe bend is connected to the two pipes by flanges. The flanges are held together by flange bolts. Assume the density of water is 1000 kg/m³. At the inlet to the bend, the pressure is P₁ = 350 kPa, the pipe diameter is D₁ = 25 cm, and the water velocity is V₁ = 2.2 m/s. At the outlet of the bend, the pressure is P₂ = 120 kPa and the pipe diameter is D₂ = 8 cm. The weight of the pipe bend and the water in the bend may be neglected for this analysis. 1 5 G 2 (a) Determine the velocity of the water at the outlet (i.e., at Section 2). Hint: Use CoM principles (and don't forget to draw a system diagram!). (b) Draw appropriate system diagrams to determine the total force acting on the flanges (to keep the system in equilibrium).

There is a small hill between the two reservoirs with the highest point at 500 m along the pipe from A.

Question 3 A pipe of 150mm bore is delivering water at the rate of 7500 dm/min at a pressure of 820 kN/m?.It connects by a gradually expanding pipe to a main of 300 mm bore which runs 3m above it. Find the pressure in the 300mm main?
A vertical pipe is shown in figure 1 below. The pipe tapers from 50 mm in diameter to 25 mm in diameter. If 2 liters of water per minute flow upwards through the pipe the pressure difference across the pipe is 35 kpa. Calculate the flow downwards through the pipe if the pressure across the pipe is to be zero. The losses across the pipe are given by h1=k((v2) ²-(v1)²)/2g,where v1 and v2 are the velocities in the 50 mm and the 25 mm sections respectively.
