Finding the diameter in the walls of a pipe (related to current)

However, you also need to consider the area of the water flow in the center of the pipe. To find the area of the copper part, you can use the formula ∏r^2 where r is the radius of the pipe. To find the area of the water flow, you can use the same formula but with the inside radius of the pipe. In summary, to find the area between the inside and outside walls of a copper pipe used in high-current electromagnets, you can use the formula ∏r^2 for the copper part and the same formula with the inside radius for the water flow. This will give you the total area of the pipe.

Homework Statement


The windings of high-current electromagnets are often made of copper pipe. The current flows in the walls of the pipe, and the cooling water flows in the interior of the pipe. Suppose the copper pipe has an outside diameter of 0.8 cm and inside diameter of 0.5 cm


Homework Equations


∏r2


The Attempt at a Solution


I need to find the area between the inside pipe where the cooling water has and the outside wall. To do this, should I simply subtract the area of the 0.8 cm diameter pipe by the area of the 0.5 cm diameter pipe? Or it's something more complicated than that?

You have the right approach. That will get you the area of the copper part.
 

Related to Finding the diameter in the walls of a pipe (related to current)

What is the purpose of finding the diameter in the walls of a pipe?

The diameter of a pipe is an important measurement in determining the flow rate and capacity of a pipe. It is also essential in selecting the appropriate pipe size for a specific application.

What is the most accurate method for finding the diameter in the walls of a pipe?

The most accurate method for finding the diameter in the walls of a pipe is by using specialized tools such as calipers or micrometers. These tools can provide precise measurements of the pipe's internal diameter.

What are the potential challenges in finding the diameter in the walls of a pipe?

One potential challenge is that the pipe may be irregularly shaped, making it difficult to measure the diameter accurately. Another challenge is that the pipe may be located in a hard-to-reach or confined space, making it challenging to take measurements.

What are some common techniques for finding the diameter in the walls of a pipe?

Some common techniques for finding the diameter in the walls of a pipe include using a tape measure or ruler to measure the outside diameter and subtracting the wall thickness, using a string or wire to measure the circumference and then calculating the diameter, or using specialized tools such as a pipe gauge or pit gauge.

What factors can affect the accuracy of finding the diameter in the walls of a pipe?

The accuracy of finding the diameter in the walls of a pipe can be affected by factors such as the type of material the pipe is made of, the condition of the pipe (e.g., rust or corrosion), and the measurement method used. It is essential to consider these factors and use the most appropriate measurement technique for accurate results.
