Pipeline Speci?cations Design will need to examine: The tradeoff between the cost of compression [a
function of minimum driver power) and the cost of pipeline [a function of nominal pipe size). Following to
be calculated: Nominal Pipe Size (NPS) Wall Thickness (WT) The frictional loss in the pipeli... 

Determine:

• Inside diameter
• Pressure profile

Design Objective: Determine nominal pipe inside diameter to ensure sufficient process flow, and ensure
sufficient process pressure, at point of delivery Design Consideration: Upper end of pipe size range -
maximum flow rate - minimum inlet pressure - minimum outlet pressure Lower end of pipe ...
