Metal removal rate from volume of crater Solution

Follow our step by step solution on how to calculate Metal removal rate from volume of crater?

FIRST Step Consider the formula

Z w = V \cdot f c

Next Step Substitute values of Variables

∴

Z w = 50000mm² \cdot 1600cycle/s

Next Step Convert Units

∴

Z w = 0.05m² \cdot 1600Hz

Next Step Prepare to Evaluate

∴

Z w = 0.05 \cdot 1600

LAST Step Evaluate

∴

Z w = 80m³/s
