Friction Velocity given Dimensionless Wave Height Solution

STEP 0: Pre-Calculation Summary

Formula Used

Friction Velocity = sqrt(([g]*Characteristic Wave Height)/Dimensionless Wave Height)
V_f = sqrt(([g]*H)/H')
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Friction Velocity - (Measured in Meter per Second) - Friction Velocity, also called shear velocity, is a form by which a shear stress may be re-written in units of velocity.
Characteristic Wave Height - (Measured in Meter) - Characteristic wave height is originally taken as the significant wave height but more recently taken as the energy-based wave height.
Dimensionless Wave Height - Dimensionless Wave Height is denoted by H' symbol.

STEP 1: Convert Input(s) to Base Unit

Characteristic Wave Height: 110 Meter --> 110 Meter No Conversion Required
Dimensionless Wave Height: 30 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_f = sqrt(([g]*H)/H') --> sqrt(([g]*110)/30)

What is Geostrophic wind?

The Geostrophic flow is the theoretical wind that would result from an exact balance between the Coriolis force and the pressure gradient force. This condition is called geostrophic equilibrium or geostrophic balance. The geostrophic wind is directed parallel to isobars.
