A pipeline that transports oil at 40°C at a rate of 3 m 3 /s branches out

Question:

A pipeline that transports oil at 40°C at a rate of 3 m³/s branches out into two parallel pipes made of commercial steel that reconnect downstream. Pipe A is 500 m long and has a diameter of 30 cm while pipe B is 800 m long and has a diameter of 45 cm. The minor losses are considered to be negligible. Determine the flow rate through each of the parallel pipes.
