Way back when I went to college (no, the dinosaurs were not roaming the earth then), a standard BS (that’s a Bachelor of Science, folks) in chemical engineering demanded the completion of 144 credits. Given that this is a technical program- and three hours labs only yielded 1 credit- plus there were 14 lab courses to be completed), it meant some 2580 hours of instruction. Part of that curriculum included two courses in aeronautical engineering.
