  1. Flow Characteristics • Viscosity determined through index matching, (550 SSU, 109 cP, 0.109 Pa-s) • Much higher than water (1 cP) • Flow tested by Army is from 2-10 L/min • Using Reynolds number matching, 6-32 GPM • Pressure loss through system ranges from 20 psi to 50 psi • Calculated using Poiseuille flow

  2. Positive Displacement vs. Centrifugal Conclusion: PD pumps provided better flow control, regardless of pressure and handle high viscosities. Graph Credit: pumpschool.com
