Need help ASAP with thermo problem!!?

This is a grossly oversimplified system. All you need to do is determine the cycle that applies and work thru the equations. If you're lost, my doing this for you will help you not at all. There are plenty of examples of this "problem" in the text and handbooks. This "system" won't really work.... saturated steam to a turbine will only destroy the turbine and be a safety hazard.
