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(Fc, form/0.5*ρwater*Cc, form*B*T*cos(θc))
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
Longshore Current Speed - (Measured in Meter per Second) - Longshore Current Speed is the speed of a longshore current, which is a current that flows parallel to the shore within the zone of breaking waves.
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(Fc, form/0.5*ρwater*Cc, form*B*T*cos(θc)) --> 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
