Memory requirements for concurrent users in Oracle 11i ERP

I am looking at installing some new modules in our Oracle 11i ERP environment. Can I get some statistics regarding the memory requirements for each concurrent user?

The V$PROCESS view shows the amount of PGA memory used (PGA_USED_MEM) for each process in the database. You can map this to the session by a query similar to the following:
SELECT sid,username,pga_used_mem
FROM v$session s, v$process p
WHERE s.paddr=p.addr;
