Question:
The water system in a suburban area consists of an old 200-mm pipeline 760 m long which conveys water from a pump to a reservoir whose water surface is 107 m higher than the pump. Water is pumped at the rate of 0.07 m3/s. Determine the horsepower saved by replacing the old pipe with a new 250-mm pipe. Assume the value of f as equal to 0.033 and 0.022, respectively, for the old and new pipes. Neglect losses of the head except for friction head. Ans: 22.82 hp Problem 7 - 77 Paint issues from the tank in shown at Q = 45 ft/h. Assume laminar flow conditions and neglect entrance and exit losses. L = 6 ft, d = V2 in (a) What is the velocity of flow in the pipe? Ans: 9.167 ft/s (b) Determine the head lost in the pipe. Ans: 7.695 feet (c) Determine the kinematic viscosity of the paint in ft/s
