1- Water flows through a turbine to generate power at a rate of 3250 gpm. The pressure at point A is 23 psi and at point B is -4.9 psi. The friction energy loss between points A and B is 2.5 times the velocity head in pipe A. The diameter of pipe A is 0.9948 ft. Assume that the turbine has an efficiency of 100%. This turbine must generate enough to power a 40-kW electrical demand. Calculate the minimum diameter for pipe B (Use the attached table for the pipe size selection). 1 kW=734.3 ft.lb/s Sch 80 Imperial Pipe diameter inches Inside diameter inches Inside diameter feet Flow area (ftsg) 0.25 0.302 0.02517 0.000497 0.375 0.423 0.03525 0.000976 0.5 0.546 0.0455 0.001625 0.75 0.742 0.06183 0.003 1 0.957 0.07975 0.00499 1.25 1.278 0.1065 0.00891 A 1.5 1.5 0.125 0.01227 2 1.939 0.1616 0.02051 2.5 2.323 0.1936 0.02944 3 2.9 0.2417 0.0459 3.5 3.364 0.2803 0.06174 4 3.826 0.3188 0.07986 5 4.813 0.4011 0.1263 3 ft 6 5.761 0.4801 0.181 Turbine 8 7.625 0.6354 0.3174 10 9.564 0.797 0.4986 12 11.376 0.948 0.7056 14 12.5 1.042 0.8521 16 14.314 1.193 1.117 18 16.126 1.344 1.418 20 17.938 1.495 1.755 24 21.564 1.797 2.535 B
