Question

formula for area of pipe ​

Answer 1

Answer:

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.

Area of pie = 3.14 × L ×D

Answer 2

TSA of pipe $\bf = 2\pi \: rh$

Given:

• A pipe.

To find:

• Find the surface area of the pipe.

Solution:

Concept/Formula to be used:

• A pipe is a hollow cylinder.
• Assuming the thickness of the material through which pipe is to be made as small as possible.

Step 1:

Write the surface area of the cylinder.

The total surface area of cylinder: Curved surface area+ Area of top and bottom.

Curved surface area of cylinder: $\bf 2\pi \: rh$

here,

r: Radius

h: Height

Area of top and bottom of cylinder: $\pi {r}^{2} + \pi \: {r}^{2}$

Total surface area of cylinder$\bf = 2\pi \: rh + 2\pi {r}^{2}$

Step 2:

Find the total surface area of the pipe.

We know that,

Pipe is open from both ends.

So,

We have to remove or subtract $2\pi {r}^{2}$ from the total surface area of cylinder.

Total surface area of pipe : Curved surface area of cylinder.

Total surface area of pipe$= 2\pi \: rh$

Thus,

$\bf \text{\bf TSA of pipe}= 2\pi \: rh$
