I have an engine air mass flow rate (322 kg/s) which I would like to convert to a corrected mass flow rate at 10000 feet.
I have tried using the equation found here. However, this article lacks any sources and I have struggled to find any other reliable sources online.
I have made an attempt using the equation in the article but have gotten a greater mass flow than 322, which doesn't make sense.
Is the equation in the article correct or am I just calculating this wrong?
For 10000 ft I get:
Temperature 268K Pressure 69.6817 KPa
So Theta = 0.9301 and Delta = 0.6877
Which gives a corrected mass flow of 451 kg/s.
