Two reservoirs have a difference in height of 10 meters at thefree surface. They are connected by two pipes in series; the firsttube is 20 m long and has a diameter of 6 cm. The second tube is 10meters long with a diameter of 10 cm. At the change in tubes, anexpander (θ = 20°) is fitted, there are two 90° bends (flanged) inthe second section of piping Assuming f = 0.0216 for both tubes,what is the flow rate?
