Current Efficiency given Gap between Tool and Work Surface Solution

Follow our step by step solution on how to calculate Current Efficiency given Gap between Tool and Work Surface?

FIRST Step Consider the formula

η e = h \cdot r e \cdot ρ \cdot \frac{V f}{V s \cdot e}

Next Step Substitute values of Variables

∴

η e = 0.25mm \cdot 3Ω*cm \cdot 6861.065kg/m³ \cdot \frac{0.05mm/s}{9.869V \cdot 2.9E-7kg/C}

Next Step Convert Units

∴

η e = 0.0002m \cdot 0.03Ω*m \cdot 6861.065kg/m³ \cdot \frac{5E-5m/s}{9.869V \cdot 2.9E-7kg/C}

Next Step Prepare to Evaluate

∴

η e = 0.0002 \cdot 0.03 \cdot 6861.065 \cdot \frac{5E-5}{9.869 \cdot 2.9E-7}

Next Step Evaluate

∴

η e = 0.900847184852739

LAST Step Rounding Answer

∴

η e = 0.9008
