Sorry, this question can not be answered without an on site visit by an engineer or architect.

No one here can answer the question with certainty ---call a local engineer for an answer you can count on.--Mike---

You need to determine with some degree of accuracy how much load that wall is supporting. That is going to be not only a function of what is above it, but the design and construction of what's above it and how the load is distributed by the framing and/or other supporting structure. Unless you are an engineer it's fairly certain you won't have the expertise to calculate that.

In addition, 10' is a not inconsiderable span to support. You'll need specs for the supporting posts(size for steel, pcl, etc.) at each end of that span and just as importantly, an engineering solution for what is going to support those posts.

I opened up 14' of wall in our house this past fall, and in addition to needing 4 16" LVLs I needed new footings in the basement and 6" steel columns directly under the supporting posts.

Don't try and DIY on the design solution. Get it wrong and your mistake could be both expensive and fatal.
