A complex water delivery system has been incorrectly designed in an island luxury resort. It consists of a variety of different pipe diameters over the many floors in this multi-storey high-rise building. Four positions throughout this system with a common discharge of 0.4x10-3 m3/s are to be analysed in an "ideal" way by ignoring all losses so that the energy line has no slope. The four different positions are labelled A to D. Positions A, B and C have diameters of 12, 235 and 275 mm, respectively. Position A is located 38 m above a local datum. The pressure at position B is 168 kPa. The pressure at position C is 325 kPa and the elevation of C is 2 m above datum. At position D, the turbulent flow has a velocity of 4.89 m/s, and the elevation above datum is 40 m. Provide your complete numerical working to display how you calculated the : pressure at A, elevation head at B, velocity head at C, pressure head at C, pressure at D.
Explanation / Answer
use conservation of energy and as motion is in downward direction ...conservation of momentum in horizontal direction......thanx please rate 5
