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.
Water flows at the rate of 5 ft/s through an inclined pipe. At point A, where the diameter is 12 inches, the pressure is 15 psi. At point B, the diameter is 6 inches and the center of the pipe is 2 feet lower than at point A. a. Draw a clear diagram of the pipe system that indicates the following: (a-1) water flow reflecting the quantities involved in describing fluid flow and (a-2) the object of interest and the quantities that describe Bernoulli's equation. b. Write the Bernoulli's Equation using subscripts U ad L for the upper and lower points respectively and determine the pressure at point B?
