5. Two large water reservoirs with a water level difference of 12 m are joined together with two pipes connected in series so that water flows from the upper reservoir to the lower one. The pipe exiting the upper reservoir is 200 mm in diameter, 300 m long, and has a friction factor of 0.024. The other pipe that enters the lower reservoir is 100 mm diameter, 100 m long and has a friction factor of 0.032.
