This formula uses 2 Functions, 6 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
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
Average Current Speed - (Measured in Meter per Second) - The Average Current Speed [length/time] defined as the speed of Ocean currents that are continuous, predictable, directional movement of seawater.
Skin Friction of a Vessel - Skin Friction of a Vessel is defined as the friction at the surface of a solid and a fluid in relative motion.
Density of Water - (Measured in Kilogram per Cubic Meter) - The Density of Water is mass per unit of water.
Skin friction coefficient - Skin friction coefficient is an important dimensionless parameter in boundary-layer flows. It specifies the fraction of the local dynamic pressure.
Wetted Surface Area - (Measured in Square Meter) - Wetted Surface Area [length^2] is the total area of outer surface in contact with the surrounding water.
Angle of the Current - Angle of the Current Relative to the Longitudinal Axis of the Vessel.
STEP 1: Convert Input(s) to Base Unit
