Hydraulic Terminology

  1. Hydraulics
    The study of fluids at motion and at rest
  2. Friction Loss
    Loss of pressurein hose, fittings, standpipes etc., due to turbulence created between the moving water and the inside surfaces. "The consumption of energy"
  3. Gallons Per Minute
    The quantity of water flowing measured in gallons per minute. "Volume or quantity"
  4. Pressure
    Water force measured in pounds per square inch (psi). "Force"
  5. Head Pressure
    Pressure due to elevation of water, also termed back pressure. The weight of water combined with gravitational force creates pressure. "Pressure generated by elevation"
  6. Static Pressure
    Pressure which exists in a water system when no water is flowing. "Stored pressure energy when water is at rest"
  7. Residual Pressure
    Pressure which remains in a water supply when water is flowing. "Remaining pressure"
  8. Flow Pressure
    Forward velocity pressure at a discharge opening when water is flowing. The rate of flow (velocity) of water as it emerges from a discharge opening. "Forward pressure"
  9. Nozzle Pressure
    The actual pressure which exists at the nozzle of a fire hose or appliance.
  10. Discharge Pressure
    Refers to the pressure which existsat the discharge side of a pump. "Water pressure as it exits the pump"
  11. Net Discharge Pressure
    Refers to the actual pressure created by the pump. The difference between the intake and discharge pressures. "Pressure generated by the pump"
  12. Intake Pressure
    The pressure which exists at the intake side of the pump. "Water supply"
  13. Velocity
    Pressure energy directed in a given direction. Usually measured in feet per second. "The speed at which water travels"
  14. Nozzle Reaction
    When water is discharged from a nozzle, a reaction in the opposite the flow takes place at the nozzle, this results in a recoil or "Kick Back"
