We do not have 2019 data yet and that was the year EWS reservation has started. But in 2018 for OC Boys, the cut off ranks for JNTUA have been as follows:

Chemical Engineering: 11712

Civil Engineering: 8973

CSE: 4424

ECE: 4854

EEE: 5464

MEC: 7444

Now this is 2018 data of OC Category. Loosely based on this, with a rank of 10,000 you might get a seat in JNTU A within Chemical Engineering branch. Having said that cut offs change every year and are dependant on various factors.
