Enthalpy Concentration Diagram Example

I just LOVE your calligraphy

at 5:49 in the video, you draw a line from one end of the isothermal line at 82 degrees down to the freezing point line, and you read the liquid stream enthalpy from that point. is this a mistake? I thought the enthalpy of the vapor stream was read from the dew line, and the enthalpy of the liquid stream is read from the boiling line.

I dont understand how you got 67 kcal if the straight line is goes to the 80 kcal on y?

[@julio95]

me too

Good question. This graph is difficult to read. I think the line you are looking at isn't a straight line. If you draw a line from that dot, parallel to the x-axis (or perpendicular to the y-axis, if that's easier), it comes to approximately 67 kcal/kg.
