Hi, I need with the following question. Argon gas expands in an adiabatic turbine from 3MPa and 750 C to .2 MPa at a rate of 5 kg/s. Neglect KE and PE effects. Find maximum power output. I know I need to first find the temperature of state two and then use that to solve for h2 (I have already solved for h1) then plug it in to W=mass flow rate(h1-h2) to solve for the work and go from there but I am having a problem finding T2. Any help would greatly be appreciated.
