    Apply them to what? You're going to need to be a whole lot more descriptive about what you are asking in order for us to be able to help you.

    applying them to power plant
    ok.......i type the whole question for you sir.... to make you understand the problem better...
    A regenerative plant operates with steam supplied at 30 bar and 300 C,and condenser pressure of 0.08 bar. The extraction point for two heater (one close and one open)are at 3.5 bar and 0.7 bar resp. calculate the thermal efficiency of the plant neglecting pump work.
