If we had 2 wind turbines one directly ahead of the other, would the wind exitting from turbine 1 produce the same power in turbine 2?

Depends on the diameter and pitch of the blades.

I agree that the 1st wind turbine will slow the wind it is capturing - that's just conservation of energy as some other answers have already explained. Typically wind turbines are spaced somewhere in the range of 5-6 rotor diameters apart. For example, a 1.5 MW turbine with 40m blades (roughly 80m rotor) will probably be sited 400-500m from the next turbine. As previously mentioned, the fluid dynamics also play a key role. When wind passes by a rotating turbine and it's tower, the exiting wind contains higher turbulence levels than that which is in front of the turbine. This also can affect the efficiency of the total wind farm system, as most turbines must operate at lower than their design wind speed if the turbulence level is higher than expected.

No
the turbine actually slows the wind. If one turbine was directly behind another, the power output would be less. A lot of factors come into play of course, one of them being separation distance. If they are sufficiently separated, there would be little (if any) change. The distance of this separation depends on the conditions as well. It is a very complex problem that involves a lot of computational fluid dynamics simulations.

obiously, the "energy" in the wind exiting a turbine is less than the energy of the wind entering the turbine by the amount of work done by the turbine plus losses.
the reduced energy is manifested in properties of the exiting wind including velocity
the change in velocity will depend on the orginal velocity, the size and design of the turbine, the load (say electrical generator or whatever) on the turbine and other factors

There are some differences when connecting in series vs parallel but there are modification and additional components that will required to make these fixes and again you will still not get the complete 1:2 ratio, vanes will need to be appropriately integrated into the system.

i would assume so, if there was no friction or drag acting on the second one, and All of the air from the first one hit the second one.....but there is friction and drag, im saying no
