Question: Water at 68OF flowing at an average velocity of 9.7 ft/s through an old rusty pipe having an ID of 4.026 in. gave a net loss of head of 12.4 ft for a 51.5 ft test length. How does the experimental friction factor compare with that calculated for new commercial pipe?.
2. Shown is an open waste-surge tank with diameter of 30 ft. This tank is fed by a pump supplying a steady 100 gal/min. When the pump is first turned on, the level in the tank is 10.0 ft. The tank drains to the Ocean through 3-in. cast iron pipe as shown. Will the tank empty, overflow, or reach a constant level? Support your answer with calculation
