Wind Speed given Time required for Waves crossing Fetch under Wind Velocity Solution

Follow our step by step solution on how to calculate Wind Speed given Time required for Waves crossing Fetch under Wind Velocity?

FIRST Step Consider the formula

U = {(\frac{77.23 \cdot X^{0.67}}{t x,u \cdot {[g]}^{0.33}})}^{\frac{1}{0.34}}

Next Step Substitute values of Variables

∴

U = {(\frac{77.23 \cdot {15m}^{0.67}}{140s \cdot {[g]}^{0.33}})}^{\frac{1}{0.34}}

Next Step Substitute values of Constants

∴

U = {(\frac{77.23 \cdot {15m}^{0.67}}{140s \cdot {9.8066m/s²}^{0.33}})}^{\frac{1}{0.34}}

Next Step Prepare to Evaluate

∴

U = {(\frac{77.23 \cdot 15^{0.67}}{140 \cdot {9.8066}^{0.33}})}^{\frac{1}{0.34}}

Next Step Evaluate

∴

U = 3.93916236256463m/s

LAST Step Rounding Answer
