Output and exhaust temperature of an Ammonia based turboexpander!

[pranabjyoti]

I have got data from the manufacturer of turboexpanders regarding an Ammonia based turboexpander. For a specific amount of Ammonia input at 4 barA pressure and 27°C, the output was around 1.5 MW and the exhaust will be at -34°C. Now, I want to know if the pressure of the input has been raised to 8 barA and the other parameters has been kept unchanged, what can be the possible output then.
