Water flow through a 40 in diameter pipeline at 75 lbmmin Ca

Water flow through a 4.0 in. diameter pipeline at 75 lbm/min. Calculate the mean velocity. Assume T = 60 F

>> Mass Flow Rate = 75 lbm/min = 1.25 lbm/sec

and at 60 F, Density of Water = 1.938 lbm/ft³

>> Area, A = pi*4²/4 = 12.566 in²

As, Discharge or Volumetric Flow Rate = Mass Flow Rate/Density = Area * Velocity

=> Putting all values ,

=> 1.25/(1.938/12³) = 12.566*V

>> Solving,

V = 88.696 in/sec = 7.39 ft/sec .... ANSWER...
