Plug in L and D into the following equation to calculate the surface area of the pipe:
3.14 x L x D
. For example, if you had a pipe with a length of 20 feet and a diameter of 2 feet, you would get 3.14 x 20 x 2 and find that the surface area of the pipe equals 125.6 square feet.
How do you find the area of a tube?
- generally C = 2πr, therefore,
- C
1
= 2πr. … - C
2
= 2πr.
How do you calculate the cross sectional area of a pipe?
- Subtract the squares of inner diameter from the outer diameter.
- Multiply the number with π.
- Divide the product by 4.
What is the cross sectional area of a 4 pipe?
Square this radius. In the example, 4^2 = 16 square inches. Multiply the result by pi, which is approximately 3.142 — 16 x 3.142 =
50.27 square inches
. This is the pipe’s cross-sectional area.
What is the area of a 2 pipe?
| Nominal Pipe Size (in) Circumference (in) Section Area (sq.in.) | 1 3.142 0.785 | 1 1/4 3.927 1.227 | 1 1/2 4.712 1.767 | 2 6.283 3.142 |

What is a formula of cylinder?
The formula for the volume of a cylinder is
V=Bh or V=πr2h
. The radius of the cylinder is 8 cm and the height is 15 cm. … Therefore, the volume of the cylinder is about 3016 cubic centimeters.
What is area of Rod?
As a unit of area, a square perch (the perch being standardized to equal 161⁄2 feet, or 51⁄2 yards) is equal to a square rod,
301⁄4 square yards
(25.29 square metres) or 1⁄160 acre.
How do you calculate the weight of a tube?
- Round steel pipe and tube: 10.68 x (OD – WT) x WT.
- Square and Rectangular steel tube: (2 x (WT) x (h + w – 8 x (WT)) + 9.4248 x (WT x WT)) x 3.40277.
How do I calculate flow rate?
Flow rate is the volume of fluid per unit time flowing past a point through the area A. Here the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is ̄ ̄ ̄v=d/t v ̄ = d / t so that the flow rate is
Q=Ad/t=A ̄ ̄ ̄v Q = Ad / t = A v ̄
.
How do you figure out a diameter?
- Diameter = Circumference ÷ π (when the circumference is given)
- Diameter = 2 × Radius (when the radius is given)
- Diameter = 2√[Area/π] (when the area is given)
What is cross section area?
The cross-sectional area is
the area of a two-dimensional shape that is obtained when a three-dimensional object – such as a cylinder – is sliced perpendicular to some specified axis at a point
. … For example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.
What are the formulas for area and perimeter?
| Figures Area Formula Variables | Area of Rectangle Area = l × w l = length w = width | Area of Square Area = a 2 a = sides of the square | Area of a Triangle Area = 1/2 b×h b = base h = height | Area of a Circle Area = πr 2 r = radius of the circle |
|---|
What is the formula to calculate area of land?
Multiplying length by width gives you the area, or the space inside the boundary of your property. Acreage is simply one measure of area. An easy way to remember the formula for area is
A (area) = L (length) x W (width)
, which is the exact calculation done in this step.
What is the area of this shape?
| Shape Area of Shapes – Formula | Rectangle Area of a rectangle = length × width = l × w square units | Circle Area of a circle = π r 2 square units | Triangle Area of a triangle =12×b×h 1 2 × b × h square units | Parallelogram Area of a parallelogram = base × height = b × h square units |
