Question

A large-capacity faucet is to be connected to a water main by 20-mm-diameter copper tubing as shown in figure. The copper tubing has an estimate surface roughness of 0.003 mm, and local head losses are created by the corporation stop (C-stop), four bends, and the faucet itself. The faucet exi diameter of 12 mm. What minimum pressure in the water main is require obtain a desired flow rate of 50 L/min when the faucet is wide open? At 20°C, the properties of water are ρ-998 kg/m2, and its kinematic viscosity, v- 1.0 *10° m'/sec. Gravity acceleration, g 9.81 m/sec2] [If the flow is turbulent, use attached Moody-Chart to figure the friction coefficient of the tubes d equivalent t has a d to Bend 4m Fauuet , Bend 5m Bend tina- Bonds 12 Faucet 10 Water main 3.5m Bend C-stop
