    Is this Thermodynamic Cycle Possible and Reversible?

    The statement I was referring to was the first law. So I was just seeing if that was proof enough that it doesn't violate the first law. As far as the reversibility thing, I see what you mean. I am still pretty confused on this one.

    Is this Thermodynamic Cycle Possible and Reversible?

    Ahhh Ok great, thanks Red. So with that thinking then- Since the engine is doing the work, that means that W=-2000, So dU=2000-2000=0. So 2000 still = 2000 So am i correct in saying that this means that this statement is valid? Is my reason correct for why it is irreversible as well? Once...

    Is this Thermodynamic Cycle Possible and Reversible?

    Homework Statement Determine Whether or not this cycle violates the first law and if it is reversible, irreversible, or not possible. 2000kW or power are produced by taking 3000 kW of heat transfer from a 750C reservior and rejecting 1000kW of heat to a 20C reservoir. Homework...
