Hey guys! Was wondering if someone could help me out. I'm doing a thermodynamics topic and have an issue explaining the following :
I conducted and experimental procedure involving a boiler apparatus. (Similar to this one >> http://www.armfield.co.uk/th3_datasheet.html" ) Now the idea was to find the pressure and temperature for a set of data points. These data points are then to be compared to the "Steam Table" data points.

The red line is the experimental results and the blue is the data gained from the steam tables. There is roughly a 4 degree Celsius difference at each pressure point.
I have to explain why there is a variance in my results? Now human error or apparatus error is just not good enough for the explanation. Is there a concrete thermodynamical explanation?
Help would be greatly appreciated!
Ohh on the side note: How can I improve the experimental apparatus or conditions to get closer to the steam table results??
