Wetted Surface Area of Vessel Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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).
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.
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.

STEP 1: Convert Input(s) to Base Unit

Vessel Draft: 1.68 Meter --> 1.68 Meter No Conversion Required
Waterline Length of a Vessel: 7.32 Meter --> 7.32 Meter No Conversion Required
Displacement of a Vessel: 27 Cubic Meter --> 27 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S^' = (1.7*T*l_wl)+((35*D)/T) --> (1.7*1.68*7.32)+((35*27)/1.68)

Evaluating ... ...

S^' = 583.40592

STEP 3: Convert Result to Output's Unit

583.40592 Square Meter --> No Conversion Required

FINAL ANSWER

583.40592 ≈ 583.4059 Square Meter <-- Wetted Surface Area of Vessel

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.
