A water faucet is to be added by running a line from a water main at 300 kPa. The diameter (cm) of the cast iron pipe is to be determined. A gate valve is placed near the attachment to the water main, and the faucet includes an angle valve. Assume 16 m of pipe length includes 3 regular 90 degree, threaded elbows, with negligible change in elevation. If the maximum flow rate is 0.0014 m3/s, determine the minimum pipe diameter that should be specified.
