A main pipe divides into two parallel pipes which again form one pipe. Pipe 1 is 2000 m long and 1.0 m in diameter; pipe 2 is 2000 m long and 0.8 m in diameter. The total flow in the main is 3.0 m^{3}/s and the coefficient of friction is the same (f′ = 0.005) for each pipe. Find the rate of flow in each parallel pipe (answers in m^{3}/s).
