Average Current Speed for Form Drag of Vessel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Longshore Current Speed = sqrt(Form Drag of a Vessel/0.5*Water Density*Form Drag Coefficient*Vessel Beam*Vessel Draft*cos(Angle of the Current))
V = sqrt(F_{c, form}/0.5*ρ_water*C_{c, form}*B*T*cos(θ_c))
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)
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

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).
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.

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
Angle of the Current: 1.15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V = sqrt(F_{c, form}/0.5*ρ_water*C_{c, form}*B*T*cos(θ_c)) --> sqrt(150/0.5*1000*5*2*1.68*cos(1.15))

Evaluating ... ...

V = 1434.84379012356

STEP 3: Convert Result to Output's Unit

1434.84379012356 Meter per Second --> No Conversion Required

FINAL ANSWER

1434.84379012356 ≈ 1434.844 Meter per Second <-- Longshore Current Speed

What is Mooring in Shipping?

Mooring is a procedure to anchor the ship to a fixed or floating element and keep it connected during loading or unloading operations. Safe mooring must withstand several forces, such as wind, the current, the tide and waves.
