Here is how the Intensity Ratio equation looks like.

1.0115 = 1 + (1.5 \cdot (\frac{6}{750 + 35}))

1.0115 = 1 + (1.5 \cdot (\frac{6rev/s}{750rev/s + 35rev/s}))

1.0115 = 1 + (1.5 \cdot (\frac{6}{750 + 35}))

Intensity Ratio Solution

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

FIRST Step Consider the formula

Ratio Io/I = 1 + ([Q] \cdot (\frac{K q}{K f + K NR}))

Next Step Substitute values of Variables

∴

Ratio Io/I = 1 + (1.5 \cdot (\frac{6rev/s}{750rev/s + 35rev/s}))

Next Step Convert Units

∴

Ratio Io/I = 1 + (1.5 \cdot (\frac{6Hz}{750Hz + 35Hz}))

Next Step Prepare to Evaluate

∴

Ratio Io/I = 1 + (1.5 \cdot (\frac{6}{750 + 35}))

Next Step Evaluate

∴

Ratio Io/I = 1.01146496815287

LAST Step Rounding Answer

∴

Ratio Io/I = 1.0115
