a) What is the flow in the pipeline?
b) It is required to increase the flow to the downstream reservoir by 30%. This is to be done
adding a second pipe of the same dia (that connects at some point along the old pipe and runs
down to the lower reservoir. Assuminge diameter and the friction factor are the same as the old
