STEP 0: Pre-Calculation Summary
Formula Used
Angle of the Current = acos((Reynolds Number for Mooring Forces*Kinematic Viscosity in Stokes)/(Average Current Speed*Waterline Length of a Vessel))
θc = acos((Rem*ν')/(Vc*lwl))
This formula uses 2 Functions, 5 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)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)
Variables Used
Angle of the Current - Angle of the Current refers to the direction at which ocean currents or tidal flows approach a coastline or a coastal structure, relative to a defined reference direction.
Reynolds Number for Mooring Forces - The Reynolds Number for Mooring Forces refers to the number for mooring forces involved in understanding the flow conditions around mooring lines or structures.
Kinematic Viscosity in Stokes - (Measured in Square Meter per Second) - Kinematic Viscosity in Stokes is defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.
Average Current Speed - (Measured in Meter per Second) - Average Current Speed for propeller drag refers to calculating propeller drag in water depending on factors, including the type of vessel, size and shape of propeller, and operating conditions.
Waterline Length of a Vessel - (Measured in Meter) - Waterline Length of a Vessel is the length of a ship or boat at the level where it sits in the water.
STEP 1: Convert Input(s) to Base Unit
Reynolds Number for Mooring Forces: 200 --> No Conversion Required
Kinematic Viscosity in Stokes: 7.25 Stokes --> 0.000725 Square Meter per Second (Check conversion ​here)
Average Current Speed: 728.2461 Meter per Hour --> 0.202290583333333 Meter per Second (Check conversion ​here)
Waterline Length of a Vessel: 7.32 Meter --> 7.32 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
θc = acos((Rem')/(Vc*lwl)) --> acos((200*0.000725)/(0.202290583333333*7.32))
Evaluating ... ...
θc = 1.47271693471467
STEP 3: Convert Result to Output's Unit
1.47271693471467 --> No Conversion Required
FINAL ANSWER
1.47271693471467 1.472717 <-- Angle of the Current

What causes Skin Friction?

The Skin friction drag is caused by the viscosity of fluids and is developed from laminar drag to turbulent drag as a fluid moves on the surface of an object. Skin friction drag is generally expressed in terms of the Reynolds number, which is the ratio between inertial force and viscous force.
