Here is how the Lifetime Ratio equation looks like.

8.2 = 1 + (6 \cdot 0.8 \cdot 1.5)

8.2 = 1 + (6rev/s \cdot 0.8s \cdot 1.5)

8.2 = 1 + (6 \cdot 0.8 \cdot 1.5)

Lifetime Ratio Solution

Follow our step by step solution on how to calculate Lifetime Ratio?

FIRST Step Consider the formula

Ratio ζ = 1 + (K q \cdot ζ o \cdot [Q])

Next Step Substitute values of Variables

∴

Ratio ζ = 1 + (6rev/s \cdot 0.8s \cdot 1.5)

Next Step Convert Units

∴

Ratio ζ = 1 + (6Hz \cdot 0.8s \cdot 1.5)

Next Step Prepare to Evaluate

∴

Ratio ζ = 1 + (6 \cdot 0.8 \cdot 1.5)

LAST Step Evaluate

∴

Ratio ζ = 8.2
