Which consequence results when lubricant viscosity decreases inside a hydraulic piston?

💡 Explanation

Lowering viscosity through increased temperature decreases resistance to flow. This enables increased fluid leakage via viscous flow through any gaps because shear stress decreases, therefore more leakage is observed, rather than reduced heating due to increased flow losses.
