Angle of Current Relative to Longitudinal Axis of Vessel for Form Drag of Vessel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle of the Current = acos(-Form Drag of a Vessel/(0.5*Water Density*Form Drag Coefficient*Vessel Beam*Vessel Draft*Average Current Speed^2))
θ_c = acos(-F_{c, form}/(0.5*ρ_water*C_{c, form}*B*T*V_c^2))
This formula uses 2 Functions, 7 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.
Form Drag of a Vessel - (Measured in Newton) - Form Drag of a Vessel refers to the resistance experienced by the vessel due to its shape and the flow of water around it.
Water Density - (Measured in Kilogram per Cubic Meter) - Water Density is mass per unit volume of water.
Form Drag Coefficient - Form Drag Coefficient is a dimensionless number that quantifies the resistance experienced by an object, such as a coastal structure or seabed feature.
Vessel Beam - (Measured in Meter) - Vessel Beam refers to the width of a vessel, such as a ship or boat, measured at its widest point.
Vessel Draft - (Measured in Meter) - Vessel Draft refers to the vertical distance between the waterline and the lowest point of a ship's hull, usually measured amidships (in the middle of the ship).
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.

STEP 1: Convert Input(s) to Base Unit

Form Drag of a Vessel: 0.15 Kilonewton --> 150 Newton (Check conversion here)
Water Density: 1000 Kilogram per Cubic Meter --> 1000 Kilogram per Cubic Meter No Conversion Required
Form Drag Coefficient: 5 --> No Conversion Required
Vessel Beam: 2 Meter --> 2 Meter No Conversion Required
Vessel Draft: 1.68 Meter --> 1.68 Meter No Conversion Required
Average Current Speed: 728.2461 Meter per Hour --> 0.202290583333333 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ_c = acos(-F_{c, form}/(0.5*ρ_water*C_{c, form}*B*T*V_c^2)) --> acos(-150/(0.5*1000*5*2*1.68*0.202290583333333^2))

Evaluating ... ...

θ_c = 2.02236308371623

STEP 3: Convert Result to Output's Unit

2.02236308371623 --> No Conversion Required

FINAL ANSWER

2.02236308371623 ≈ 2.022363 <-- Angle of the Current
