Question

Q5/ A pipeline of 600 mm diameter and 4000 m length connects two reservoirs. The difference of water levels in the reservoirs is 20 m. At a distance of 1000 m from the upper reservoir, a small pipe is connected to the pipeline. The water can be taken from the small pipe. Find the discharge to the lower reservoir if: (A) No water is taken from the small pipe. (B) 0.1 m/s of water is taken from small pipe. Take coefficient of friction f=0.005 and neglect minor losses.
