It depends on what the beam is made of.
250 Feet

That question cannot be answered without knowing the load on the beam.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
1'*1'
These calculations are not difficult, but you must know the load (including the floor weight) that will be carried. And the deflections that the appropriate building regulations allow.
That depends on what it is carrying. . .you definitely need to consult a structural engineer for this information, and having the original set of plans to show him will help. FYI. . .28 feet is a VERY long clear-span for any type of beam.
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati
