Theoretically, to get a speed estimation based on RPM, your sonarman (or yourself) would need to identify the ship first before watching it in the scope or UZO, and purlely based on the 'sound signature'. This is a technology of the mid 50s I think, and not used in WWII even if the theory was known. Sonar technology in WWII didn't yet have this 'maturity'. As a comparison: The active sonar combined with a passive one which was part of the U-boat XXI's equipment was already revolutionary at its time (1944-1945).

Identifying ships with sonar alone is AFAIK only possible in the SH5 stockgame with easy arcade settings - and surely not based on RPM listenings. However, go look in the mod download section, maybe there is such a thing.
