Which outcome during oil pipeline operation causes increased pumping costs?

💡 Explanation

Increased pumping costs in oil pipelines result from turbulent flow resistance because increased surface roughness promotes momentum transfer via eddy viscosity, therefore causing turbulent energy dissipation requiring more power, rather than other flow regimes or lowered dissipation.
