How to find the path of the feed for content type in drupal 7?
You can use the Views module to create feeds. Simply add a new display of type "Feed" and customize the view to contain only the content you want. You have to set the path in Feed Settings(enter your own path for example: type feed or any path you want).

To add a "Feed" display:

Go to your views administration and select the view you want to edit. Towards the top of the page you will see the "Displays" heading with an "+ Add" button. Click that and select "Feed" . You will then have a Feed display that is using the Default Display's settings.
