Table for Sizing[DRE-1F(For Air)]

 

How to use the chart

  • Primary pressure : 5kgf/cm2{0.5MPa}
  • Secondary pressure :  2kgf/cm2{0.2MPa}
  • Pressure differential : 3.5kgf/cm2{0.35MPa}
  • Specific gravity : 1(water)
  • Flow : 24m2/h
  • Obtain a cross point “A” by tracing down vertically from the pressure differential if 3.5kgf/cm2{0.35MPa} L on the top up to the line of Flow 24m3/h. As the point “A” is between size 50 and 65mm. select safer size 65mm.
  • Same conditions except
  • Specific gravity : 0.6
  • Obtain a cross point “B” by tracing down vertically from the pressure differential of 3.5kgf/cm2{0.35MPa} up to the line of specific gravity 1.0 and move in paralled with the slant line up to the cross point “C” on the line of the specific gravity 0.6 Trace down vertically to the point “D” in the cross line of Flow 24m3/h. As the point “D” is between size 40 and 50mm. select safer size 50mm.
