Fluid Flow in Pipes Fluid Mechanics series(part 1)

A pipe joins two reservoirs whose head difference is 10m. The pipe is 0.2 m diameter, 1000m in length and has a f value of 0.008.
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 diameter that connects at some point along the old pipe and runs down to the lower reservoir. Assuming the diameter and the friction factor are the same as the old pipe, how long should the new pipe be?
