# Homework Help: Core volume of 1 phase transformer

### Noaha

1. The problem statement, all variables and given/known data
The flux density in a single phase core type symmetric(length=breadth=height) transformer is B and flux is Φ. Can we find out the volume of core of transformer if the height of limb is h?

2. Relevant equations
Φ = B * Cross sectional area

3. The attempt at a solution
Can we say that the volume of core = 4*Cross sectional area*h - Common parts(refer the file uploaded)

Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

If you will explain what you mean by "limb" that would help. Show a "limb" on your diagram?
And what is the point of mentioning B or flux???

you can refer the below image for reference. I have mentioned flux and flux density because from these two we can find cross sectional area and with the formula i mentioned above we can find the volume of core.

Is this the right method to get value of volume of core?

B and flux depend on externally applied electrical excitation and have nothing to do with core volume or other geometrical aspects.

If we have flux and flux density as the only parameters and we are suppose to find the core volume, will the above method be right?
