Wetted Perimeter Calculator for Trapezoid
Wetted Perimeter:
Below is a table for a Wetted Perimeter of a Trapezoid Calculator. This table will allow you to calculate the wetted perimeter of a trapezoid based on the lengths of its bases and its height.
| Step | Description | Formula |
|---|---|---|
| 1 | Measure the length of the bottom base (b1) | |
| 2 | Measure the length of the top base (b2) | |
| 3 | Measure the height (h) of the trapezoid | |
| 4 | Calculate the wetted perimeter (WP) of the trapezoid | WP = b1 + b2 + 2 * √(h^2 + ((b2 – b1)^2) / 4) |
In the table, “b1” represents the length of the bottom base of the trapezoid, “b2” represents the length of the top base of the trapezoid, and “h” represents the height of the trapezoid. The formula for the wetted perimeter is derived from the properties of the trapezoid and is used to find the total length of the trapezoid’s edges that are in contact with water or liquid when it is submerged.
To use the table, follow the steps in order and substitute the given lengths of the bases and the height into the formula. The result will be the wetted perimeter of the trapezoid.

The derivation of wetted perimeter is based on measuring the length of a cross-section of a channel that is in contact with water or liquid. For a trapezoidal channel, this includes the bottom base and both side slopes.
12. What is Manning’s wetted perimeter?
Manning’s wetted perimeter is the total length of the wetted cross-sectional area of an open channel used in Manning’s equation, which relates the flow rate in the channel to the channel geometry and roughness.
13. What is wetted perimeter rectangular?
The wetted perimeter of a rectangular channel is the sum of the length of the channel’s bottom and the two side walls in contact with the water.
14. What is meant by wetted area?
The wetted area refers to the cross-sectional area of a channel or surface that is in contact with water or liquid when it is submerged.

17. What is the formula for the trapezoidal rule simplified?
The formula for the trapezoidal rule is already simplified and given as:
∫[a, b] f(x) dx ≈ (b – a) * [(f(a) + f(b)) / 2]
18. What is the trapezoidal rule?
The trapezoidal rule is a numerical integration technique used to approximate the definite integral of a function over an interval by dividing the area under the curve into trapezoids and summing their areas.
19. What is the formula for finding perimeter and area?
The formula to find the perimeter of a trapezoid is the sum of the lengths of all four sides. The formula to find the area of a trapezoid is:
Area = (1/2) * (Base1 + Base2) * h
20. How do you find the height of a trapezoid when given the sides?
To find the height of a trapezoid when given the sides, you need more information. The height can be calculated using trigonometry based on the provided side lengths and angles.
21. How do you find the other base of a trapezoid with the area?
To find the other base of a trapezoid with the area, you need the length of one base and the height. You can rearrange the area formula and solve for the other base:
Base2 = (2 * Area) / (Base1 * h) – Base1
22. How do you find the sides of a trapezoid?
To find the sides of a trapezoid, you need more information. Typically, the sides are not explicitly given in a trapezoid problem, but you can use trigonometry and the given angles and side lengths to calculate the sides.
23. How do you find the area and perimeter of an isosceles trapezoid?
To find the area of an isosceles trapezoid, you can use the formula:
Area = (1/2) * (Base1 + Base2) * h
where the bases and height of the trapezoid are known.
The perimeter of an isosceles trapezoid is the sum of all four sides, which can be calculated by adding the lengths of the two non-parallel sides and both parallel bases.
24. How do you find the area of a trapezoid without the height?
If the height of the trapezoid is not given, you cannot calculate its area with the information provided. You need either the height or additional side lengths and angles to find the area.
25. What is the difference between a trapezoid and an isosceles trapezoid?
A trapezoid is a quadrilateral with one pair of parallel sides, while an isosceles trapezoid is a specific type of trapezoid where the non-parallel sides have equal lengths.
26. What is the difference between perimeter and wetted perimeter?
Perimeter refers to the total length of the boundary of a two-dimensional shape, such as a polygon. Wetted perimeter, on the other hand, refers to the length of the cross-section of a channel or surface that is in contact with water or liquid when it is submerged.
27. What is the area divided by the wetted perimeter?
The ratio of the area of a cross-section to its wetted perimeter is known as the hydraulic radius. It is a critical parameter in fluid mechanics and is often used in calculations related to open-channel flow.
