Have you performed the calculation to see if the answer correspond with the chart details shown?

Hi Sky boy,

This is basically to convert some known values for X and y into a graphical curve so that we can extract an equation which will calculate y for any value of x.

lets say x is evap temperature and y is either capacity or power or current

I guess this is for calculating capacity, power or current for any evaporating temperature.

can we see the whole page of the formula?
