Hydrodynamic losses in pipe flow are characterized by measuring the pressure drop over a length of pipe L. If you anticipate using flow rates of 1.0 gals/min through 3/8" i.d. smooth-wall tubing, and want a pressure drop of 12 kPa, what length, L, of tubing should you use? Express your answer in meters. Note: You will note that this problem statement uses mixed units, which unfortunately are a fact of life in engineering calculations. You should know how to do...
