I have Linux machine which has 16 GB of RAM and Apache avg process size is
72 MB . What should be the ideal Max Clients so that there is better
performance we can get from server and application ?

Mem: 16410440k

Process Size : 73603 K

So max I can have ~220 process, but if I set max process availability for
Max Clients is there is any performance issues i am going to face ?

how exactly did you find this "process size"?
Most of OSes have two process sizes: one counts all addess space eaten by
process, second counts only that part that is not shared between processes.
They may differ very much.

Yeah that's rite . I wrote script to monitor the httpd process and RSS . I
could see process size lies in specific range that's between 70-75 KB. I
know there can e variation .
