F/Downloads/Tutorial20PR20%2020.pdf + to page Page Question 2 21. Use the law of conservation of mass to prove the following for a fluid flowing from point 1 to point in a pipeline Where dida: (6) 2.2 Wwer at 320 K is pumped at a rate of 2.16 m'th through a 40 mm ID pipe. It goes through a length of 185 m bontonal pape. There are a number of control valves and fittings online that have a total equivalent length equal to 180 times the internal diameter. The head loss due to condenser cale isl.8m Chen the pipe roughness of 0.0002 m: 22.1 calculate the total head loss in the system and 222. determine the actual power required if the pump is 54% efficient The density of water is 1000 kg mand the viscosity of water is 065 mm (15) Question 3 A Nenton fluid flows from a tak to a distillation column long 10 m pipe with an atemal duameter of 0.2 m. The fluid flows with an average velocity of 2 ms. the pipe flow constency index k, has a value of 2.3 Punda value of 03. As the resident engineer you have been regested to calculate the apparent viscosity, the Reynolds number and the pressure drop in the pipeline for a new pumping stem The fluid density is 930 km (15)
