    Study Notes

    Calculating Height (Level)

    • The formula for calculating height (level) is: h = P / SG
      • h is the height of the liquid in inches or feet
      • P is the head pressure in inches of water or psig
      • SG is the specific gravity of the liquid

    Calculating Head Pressure

    • The formula for calculating head pressure is: P = h x SG
      • P is the head pressure in inches of water or psig
      • h is the height of the liquid in inches or feet
      • SG is the specific gravity of the liquid
