Question: How do I calculate final power / RPM when the generator is attached. Will the RPM reduce because of the weight of the generator. If yes, what will be the final RPM if a the generator weight is 15 KG

Are you intending to generate AC or DC?

109 N.m (or 10 hp) is a load.Torque produced is 109 Nm with 600 RPM without the generator (no load). As per Torque and RPM, power available at shaft (without generator) is 10HP.

If the generator requires a 10 hp input @ 600 rpm, then your turbine will produce 10 hp @ 600 rpm.Question: How do I calculate final power / RPM when the generator is attached.

If it requires less and your turbine is still producing 10 hp, the assembly will accelerate until the turbine's output equals the generator's input or when something will break.

If it requires more and your turbine is still producing 10 hp, the assembly will decelerate until the turbine's output equals the generator's input or when it completely stops.

You need to find the torque/power curve of the turbine to determine where it makes the most power.

The weight of the generator alone will not change the power output, it will only change how fast it changes speed (a heavier one will take longer to get up to speed)
