STEP 0: Pre-Calculation Summary
Formula Used
Vessel Propeller Drag = -0.5*Water Density*Propeller Drag Coefficient*Expanded or Developed blade area of a propeller*Average Current Speed^2*cos(Angle of the Current)
Fc, prop = -0.5*ρwater*Cc, prop*Ap*Vc^2*cos(θc)
This formula uses 1 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)
Variables Used
Vessel Propeller Drag - (Measured in Newton) - Vessel Propeller Drag [Force]. The incremental drag due to slipstream of running propeller is shown to decrease with air speed and increase with propeller pitch angles.
Water Density - (Measured in Kilogram per Cubic Meter) - Water Density is mass per unit of water.
Propeller Drag Coefficient - Propeller Drag Coefficient [dimensionless] is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
Expanded or Developed blade area of a propeller - (Measured in Square Meter) - Expanded or Developed blade area of a propeller [length^2] Propeller is a mechanical device for propelling a boat or aircraft, consisting of revolving shaft with angled blades attached to it.
Average Current Speed - (Measured in Meter per Second) - Average Current Speed [length/time] defined as the speed of Ocean currents that are continuous, predictable, directional movement of seawater.
Angle of the Current - Angle of the Current Relative to the Longitudinal Axis of the Vessel.
STEP 1: Convert Input(s) to Base Unit
Water Density: 1000 Kilogram per Cubic Meter --> 1000 Kilogram per Cubic Meter No Conversion Required
Propeller Drag Coefficient: 2 --> No Conversion Required
Expanded or Developed blade area of a propeller: 15 Square Meter --> 15 Square Meter No Conversion Required
Average Current Speed: 25 Meter per Hour --> 0.00694444444444444 Meter per Second (Check conversion here)
Angle of the Current: 20 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fc, prop = -0.5*ρwater*Cc, prop*Ap*Vc^2*cos(θc) --> -0.5*1000*2*15*0.00694444444444444^2*cos(20)
Evaluating ... ...
Fc, prop = -0.295198250733067
STEP 3: Convert Result to Output's Unit
-0.295198250733067 Newton --> No Conversion Required
FINAL ANSWER
-0.295198250733067 -0.295198 Newton <-- Vessel Propeller Drag

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.
