Which outcome raises the pressure when a viscous hydraulic fluid flows through a narrowing pipe?

💡 Explanation

Viscous heating occurs because the fluid's internal friction (viscosity) causes the kinetic energy to convert to heat, therefore thermal energy increases the pressure rather than the alternatives of expansion due to pressure drop or turbulence effects.
