Orange area = Vacuum Distillation Range, adapted for Solar Assisted Energy

  • * 1: Inches of Water 
  • * 2: Delta = Differential of Water Column pressure from Sea level required to distill          at the "Relative altitude" ( Or Atmospheric pressure.) 
  • * 3: Kilopascals
  • * 4: Lower end of "V.A.D" ( Vacuum Assisted Distillation )
    • Not very practical yet it requires 127 Inches of Vacuumt.
  • * 5: Normal range for "V.A.D" allows for use of ABS components.
    • In the construction of all the distillation equipment. 
  • * 6: Best safe range for "V.A.D" distillation, with a safety margin.
    • To regulate the vacuum system.
  • * 7: High end of the "V.A.D" : Less efficient than *6 as it requires more energy.
