Hello aspirant, first of all congratulations on getting 109 marks out of 180 in AEEE examination. It is difficult to predict accurately which rank you will get at this marks because the marks vs rank for AEEE exam varies drastically every year as it depends on various factors like difficulty of paper. However in my personal opinion you should be able to get mechanical at this score in Coimbatore campus but until you rank is obtained it is difficult to give accurate answer.
