Flow Measurement
Module 4
,Fluid Flow
, Reynold’s Number
If Reynolds number (Re) < 2300, the flow is
laminar;
if Re >4000 indicates turbulent flow
, Volumetric vs. Mass Flowrate
• Volumetric flow rate • Mass flow rate
V = Cross sectional m = specific density x
Area x velocity of Cross sectional
fluid area x velocity of
Units: fluid
• m3/hr Units:
• Liter/sec • kg/hr
• Gal/sec
• Ft3/min
