Why is the voltage source the most difficult to "control" in an RC circuit?

And the temperature difference of the warm and cold water.

I can clarify one of the methods, the "heat going out from the condenser divided by the compressor power". This is where you can make use of the water loop around the condenser, where both the cold water goes in and the warm water at the outlet. For its heat rejection we make use of the specific heat capacity of water and even the mass flow rate of the water.

For the COP, that is.

I have two sets of values one for each cycle performed in a lab. Of course, when using the Carnot's you acquire the highest COP as possible from the given values. However, between the enthalpies and the when heat is absorbed by the heatsink, enthalpy always has a higher value.

Why am I getting different COP's for a heatpump when I use Carnot's method, just enthalpies, and lastly both the heat going out from the condenser divided by the compressor power?

Thanks, man, I figured, but I wanted to make sure.

In a condenser and evaporator, how would I account for in my thermodynamic analysis if their pressure are gauge pressures. Do I convert them? If so, how is that done, I feel like I might've done it incorrectly.

Why would I need the temperature of the water when it's cold and warm in a heat pump cycle? Wouldn't I only need the refrigerant?
