Which risk increases when a steel pipe's internal fluid viscosity rises at a pumping station?

A)Increased pump motor cavitation damage

B)Greater frictional head-loss and pressure✓

C)Decreased pipe wall pitting corrosion

D)Reduced fluid flow turbulence onset

💡 Explanation

Increased fluid viscosity elevates the fluid's resistance inside pipes, causing greater head-loss because viscous drag increases the energy needed to sustain flow; therefore, the pressure drops along the pipe are more significant, rather than decreased turbulence or corrosion rates.
