2. Turbomachinery  Rotating element connected to a shaft  Turbine: device to extract energy from fluid stream. Pressure decrease.  Pump, fan, compressor: devices to add energy to fluid stream. Pressure increase.  Steady state: rotational speed of rotor does not vary.

3. Moving gases  Fans  Blowers  Compressors

4. Moving liquids  Pump Positive displacement Kinetic/dynamic – centrifugal pump

6. PD pump  High discharge pressure : PRV needed  High viscosity  Shear sensitive  Relatively low volume flow  Self- priming

7. Fluid Power  Elevators  Front-end loaders  Dump trucks  Fork lifts  Aircraft control surfaces  Landing gear  Dentist drill  Mining  Solvent coating  Agriculture

8. Positive Displacement Pumps

10. Positive displacement  Rotary piston  Swash plate

11. Fluid Power  Mechanical efficiency  Volumetric efficiency  Conversion factors

13. Radial pump  Centrifugal Chemical manufacture Petroleum refining Pulp & paper Water treatment Chillers for A/C

17. Pump Curve  Discharge head vs discharge rate  Shut-off head  Free discharge

18. System Head Curve  Fixed head  Variable head

20. Operating Point  Intersection pump and system head curves  Available flow rate
