Thanks, I will take some time to study them.

I would have reached the same conclusion except that the scattergram of corrected IAT-OAT vs energy out (corrected for the thermal mass of the fabric)...
We are all doing this part time! Scatter plots of IAT vs heating energy out and IAT - OAT vs heating energy out suggest 8.5kW at -2/20 and with a va...
