George, in general for a known expander's outlet pressure the gas outlet absolute temperature is given by T2 = T1*(P2/P1)^((n-1)/n) where n is the polytropic coefficient.
The generated power is then Pw = m * (h1-h2) * polytr_effcy
Hope it helps

Does anyone have experience knowing what the outlet temperatures should be.
