Two water reservoirs of height h1 = 60m and h2 = 30m are connected by a pipe that is 0.35 m in diameter. The exit of the pipe is submerged at distance h3 = 8m from the reservoir surface.

a. Determine the flow rate through the pipe if the pipe is 80 m long and the friction factor ff = 0.004. The pipe inlet is set flush with the wall.

b. If the relative roughness e/D = 0.004, determine the friction factor and flow rate.
