  1. SAMPLE SLIDES OF THE 2-DAY SEMINAR FOR ENGINEERS As you will notice there are few words on these slides, your trainer will provide you with his experience which will make these images come alive providing you with the opportunity to reflect and ask questions, the more the better. All of the presentation slides are available in a binder supplied with the seminar.

  2. PUMP SYSTEM ANALYSIS

  3. A BRIEF HISTORY OF PUMPS

  4. A BRIEF HISTORY France 1600’S

  5. HYDROSTATIC PRESSURE VS. FLUID COLUMN HEIGHT The weight of a fluid column is: Pressure (p) is equal to the weight of the fluid (F) divided by the surface area (A) at the bottom of the fluid column:

  6. PRESSURE VS. THE SHAPE OF CONTAINERS

  7. OPEN SYSTEMS AND ENTHALPY Conservation of energy demands that:

  8. PUMP TOTAL HEAD The energy balance is: The specific energy or head balance is Subsituting other expressions for head terms:

  9. THE CONTROL VOLUME APPLIED TO A REAL SYSTEM

  10. PRESSURE HEAD ANYWHERE ON THE SUCTION SIDE OF THE PUMP 0

  11. NET POSITIVE SUCTION HEAD AVAILABLE (N.P.S.H.) DEFINITION:NPSH is the head at the pump suction minus the vapor pressure head What is vapor pressure ?

  12. N.P.S.H. REQUIRED

  13. HOW IS THE N.P.S.H. REQUIRED LEVEL DETERMINED?

  14. SPECIFIC SPEED Example

  15. NPSH REQUIRED CURVES

  16. OPTIMAL SELECTION OF THE IMPELLER DIAMETER AND PUMP

  17. SYSTEM CURVE

  18. Why increase the impeller diameter when the flow must be increased?

  19. MEASURING TOTAL HEAD

  20. SOURCES OF INFORMATION ON MOTOR EFFICIENCIES DATA BASE - MotoMaster Department of Energy USA (DOE)

  21. Opportunities with higher return

  22. High efficiency motors

  23. Opportunities with higher return

  24. 6 PUMP SYSTEMS

  25. Pumps in parallel - Instability

  26. Minimum submergence of the pump inlet

  27. The effect of air (or gas) entrainment in the pump suction

  28. VARIOUS ITEMS Quick guide Viscosity ASME max. pressure allowable

  29. DYNAMIC VISCOSITY

  30. THE EFFECT OF VISCOSITY ON PUMP PERFORMANCE
