QUESTION 1 Water at the temperature of 20 flows from the basement to the second floor of a house through a pipeline length of 120 m and 0.025 m-diameter. The pipeline has 24 bends (90) and a wide-open globe valve. The water exits the pipe through a faucet of a diameter 0.012 m at a rate of 0.00175 m3 /s. If the elevation between the basement and the second floor is 16 m. Determine the pressure at the entrance of the pipe. Given the following parameters; the density and dynamic viscosity are = 998.2 /3 and = 0.001 / , respectively, = 2 for faucet, = 1.5 for bends (90), and = 10 for the wide-open globe valve, and the roughness of the pipe is = 1.5 106 .
