The low temperature is determined by the cooling medium. Physically the high pressure is determined by the pump and the high temperature by the heat transfer from the hot source. This assumes the condenser output is saturated liquid. High pressure and temperature and low pressure (or temperature). Physically the high pressure is determined by the pump and the low temperature is determined by the cooling medium. This assumes the condenser output is saturated liquid and the boiler output is saturated vapor. High pressure (or temperature) and low pressure (or temperature). How many single properties are needed to determine the cycle? Repeat the answer for a cycle with superheat.

I guess we should probably call it ranking, because this is gonna be ranking. And that's in this case is 30 30 either 30 ranking or 30 F. So the difference the difference and to temperatures in ranking or Fahrenheit, it's gonna be the same. This is this difference here in Fahrenheit because there's just a constant, um, shift between ranking and Fahrenheit. Again, this is all well, this all should be in ranking, but again, weaken use.

And that's just the high temperature divided by the change, the high temperature minus the low temperature. Ease as we go across to phase region and find that the quality factor down here when we have lowered the temperature is now 93.3% and then they wanna determine the coefficient of performance. So again, we can look at the, um, the range here of entropy. And that's at 21.4% and then likewise we can figure out the entropy here, which is 0.2 096 And then that's the same as it is that one. We know that as we can look up as three and then we can look up the the entropy values for the two faces at 30 degrees C and then So that means we can figure out where the where the the quality factor is or where we are in this region. Now we know that s three and s four are the same because it's a carnot cycle. So we cross over the two pays region here.

And again during this high temperature heat exchange, we go from the from saturated vapor too saturated liquid. He transfers at 100 the low temperature here is at 30 f. So we're going around this way and again we have we have our 22 as are working fluid, the high temperature. In this case, we have our Carnot heat pump.
