  1. Given static sources of water, calculate weight, pressure & volume, describe applicable principles of fluid pressure, and describe conditions under which drafting may take place.
  2. Given a body of water at rest or in motion, describe types of kinetic or potential energy acting on it.
  3. Given a pumping system configuration, calculate pressures acting on the system.
  4. Given an elevation head, compute the velocity head.
  5. Given an area of outlet and velocity of flow, determine the quantity of flow.
  6. Describe the factors affecting the ability to lift water.
  7. Given Freeman Formulas, calculate fire flow under various conditions.
  8. Given orifices of various shapes, calculate the fire flow.
  9. Given nozzles flowing at various pressures, calculate nozzle reaction.
  10. Describe how a water hammer occurs and how it affects pumping systems.
  11. Describe how friction loss occurs in waterways.
  12. Given common friction loss equations and flow conditions, calculate friction loss in waterways.
  13. Describe where hose lengths, hose size, velocity, and pressure are variable.
  14. Calculate friction loss for various working conditions using formulas and friction loss tables.
