Enter the values in our basic and advanced Wetted Surface Area Calculator for instant and easy calculation.
Welcome to Wetted Surface Area Calculator, a practical tool used in boat design, marine engineering to help you figure out the area of boat that’s touching the water!. This calculator helps you calculate wetted surface area of vertical or horizontal vessel, in square meters, underwater hull area etc. This calculator uses formula with easy step by step calculation.
Formula:
The formula is:
Variables:
Variable | Meaning |
---|---|
WSA | Wetted Surface Area (the total surface area in contact with water) |
WLL | Waterline Length (the length of the object at the waterline) |
B | Beam (the width of the object at the waterline) |
D | Draft (the vertical distance between the waterline and the bottom of the object) |
How to Calculate ?
To calculate the Wetted Surface Area (WSA), first measure the waterline length (WLL), which is the length of the object in contact with water. Next, measure the beam (B), the width at the waterline, and the draft (D), the vertical distance from the waterline to the bottom of the object. Add the beam and draft, then multiply the sum by the waterline length to get the total wetted surface area.
Example 1:
Given:
- Waterline Length (WLL) = 10 meters
- Beam (B) = 3 meters
- Draft (D) = 1.5 meters
Calculation | Instructions |
---|---|
Step 1: WSA = | Start with the formula. |
Step 2: WSA = | Replace WLL with 10 meters, B with 3 meters, and D with 1.5 meters. |
Step 3: WSA = | Add the beam and draft. |
Step 4: WSA = 45 square meters | Multiply by the waterline length to get the wetted surface area. |
Answer:
The wetted surface area is 45 square meters.
Example 2:
Given:
- Waterline Length (WLL) = 15 feet
- Beam (B) = 4 feet
- Draft (D) = 2 feet
Calculation | Instructions |
---|---|
Step 1: WSA = | Start with the formula. |
Step 2: WSA = | Replace WLL with 15 feet, B with 4 feet, and D with 2 feet. |
Step 3: WSA = | Add the beam and draft. |
Step 4: WSA = 90 square feet | Multiply by the waterline length to get the wetted surface area. |
Answer:
The wetted surface area is 90 square feet.
What is Wetted Surface Area Calculator ?
The wetted surface area refers to the part of an object that is in direct contact with a liquid. For ships, tanks, and pipes, this surface area plays a crucial role in determining factors like drag, heat transfer, and overall efficiency. A Wetted Surface Area Calculator allows for precise measurement based on the object’s geometry, such as cylinders or storage tanks.
This tool is also versatile, handling calculations for both vertical and horizontal tanks. You can use it in chemical processing, heat transfer analysis, or to determine surface coatings for storage tanks.
Final Words:
The Wetted Surface Area Calculator helps you figure out the surface area of objects in contact with liquids, such as tanks, pipes, and cylinders. It is invaluable in industrial applications, for chemical processing and to determine the surface coatings for storage tanks.
