exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Wind Speed - (Measured in Meter per Second) - Wind Speed is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature.
Duration of the Wind - (Measured in Second) - Duration of the Wind is the length of time during which the wind blows with a certain speed and direction.
Fetch Parameter - Fetch Parameter is often associated with the concept of fetch, which is the unobstructed distance over which the wind blows across a body of water in a constant direction.

STEP 1: Convert Input(s) to Base Unit

Duration of the Wind: 13.77 Second --> 13.77 Second No Conversion Required
Fetch Parameter: 1.22 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U = ([g]*d)/(6.5882*exp((0.0161*(ln(φ)^2)-0.3692*ln(φ)+2.2024)^0.5+0.8798*ln(φ))) --> ([g]*13.77)/(6.5882*exp((0.0161*(ln(1.22)^2)-0.3692*ln(1.22)+2.2024)^0.5+0.8798*ln(1.22)))

Evaluating ... ...

U = 3.99883001086966

STEP 3: Convert Result to Output's Unit

3.99883001086966 Meter per Second --> No Conversion Required

FINAL ANSWER

3.99883001086966 ≈ 3.99883 Meter per Second <-- Wind Speed

What is Significant Wave Height?

Significant wave height is defined as the average wave height, from trough to crest, of the highest one-third of the waves. Devised by oceanographer Walter Munk during World War II, the significant wave height provides an estimation of wave heights recorded by a trained observer from a fixed point at sea.
