Hello again, I completed the calculation for 1b which was a PB of 80% as shown in post 18.
I have attempted to plot this on a graph in the same way I plotted for question 1a but I cant seem to get it to make sense. I have taken a line from 8 mA on the Y axis. This works out at approx 16.2 bar on the x axis but it should be 14 bar. Below is a snapshot of the graph
Have I aligned the PB up correctly with the x axis or should the set point of 11 bar be inline with the 40% mark or, should the set point (desired value) be in line with the 50% measured value
Below is snap shot of the attachment, I thought I was right with this but I am missing something in the plotting or scaling of this graph I think
