Displacement of Vessel for Wetted Surface Area of Vessel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Displacement of a Vessel = (Vessel Draft*(Wetted Surface Area of Vessel-(1.7*Vessel Draft*Waterline Length of a Vessel)))/35
D = (T*(S^'-(1.7*T*l_wl)))/35
This formula uses 4 Variables

Variables Used

Displacement of a Vessel - (Measured in Cubic Meter) - Displacement of a Vessel refers to the weight of the water that a vessel displaces when it is floating.
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).
Wetted Surface Area of Vessel - (Measured in Square Meter) - Wetted Surface Area of Vessel is the total area of the outer surface in contact with the surrounding water.
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

Vessel Draft: 1.68 Meter --> 1.68 Meter No Conversion Required
Wetted Surface Area of Vessel: 600 Square Meter --> 600 Square Meter No Conversion Required
Waterline Length of a Vessel: 7.32 Meter --> 7.32 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = (T*(S^'-(1.7*T*l_wl)))/35 --> (1.68*(600-(1.7*1.68*7.32)))/35

Evaluating ... ...

D = 27.79651584

STEP 3: Convert Result to Output's Unit

27.79651584 Cubic Meter --> No Conversion Required

FINAL ANSWER

27.79651584 ≈ 27.79652 Cubic Meter <-- Displacement of a Vessel

Coefficient of Drag for Winds Measured at 10 m given Drag Force due to Wind

Go Coefficient of Drag = Drag Force/(0.5*Air Density*Projected Area of the Vessel*Wind Speed at Height of 10 m^2)

Projected Area of Vessel above Waterline given Drag Force due to Wind

Go Projected Area of the Vessel = Drag Force/(0.5*Air Density*Coefficient of Drag*Wind Speed at Height of 10 m^2)

Mass Density of Air given Drag Force due to Wind

Go Air Density = Drag Force/(0.5*Coefficient of Drag*Projected Area of the Vessel*Wind Speed at Height of 10 m^2)

Drag Force due to Wind

Go Drag Force = 0.5*Air Density*Coefficient of Drag*Projected Area of the Vessel*Wind Speed at Height of 10 m^2

Undamped Natural Period of Vessel

Go Undamped Natural Period of a Vessel = 2*pi*(sqrt(Virtual Mass of the Ship/Effective Spring Constant))

Individual Stiffness of Mooring Line

Go Individual Mooring Line Stiffness = Axial Tension or Load on a Mooring Line/Elongation in the Mooring Line

Mass of Vessel given Virtual Mass of Vessel

Go Mass of a Vessel = Virtual Mass of the Ship-Mass of Vessel due to Inertial Effects

Virtual Mass of Vessel

Go Virtual Mass of the Ship = Mass of a Vessel+Mass of Vessel due to Inertial Effects

Displacement of Vessel for Wetted Surface Area of Vessel Formula

Displacement of a Vessel = (Vessel Draft*(Wetted Surface Area of Vessel-(1.7*Vessel Draft*Waterline Length of a Vessel)))/35
D = (T*(S^'-(1.7*T*l_wl)))/35

What causes Skin Friction?

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.

How to Calculate Displacement of Vessel for Wetted Surface Area of Vessel?
