Crude oil pipeline

1
Example

• Crude oil pipeline
• Fire protection system iterative approach

2
Parallel Pipelines

• Flow
• Head loss

3
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.

4
Moving gases

• Fans
• Blowers
• Compressors

5
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
