I'd call it a backpedal when you now admit the inlet was not a vacuum

Where did you get it?))!!!! Now tell us about the bypass valve that's
needed to connect the other engines to the condenser to bypass the
turbine steam path or do you still think the main engines can run with
their outlets closed?

Bwhahahahahah big time I'd say!

You shouldn't have be so quick to Bwahahahahahaha ... when referring to
condenser vacuum, absolute pressure, measured in psia, or vacuum in
inches of mercury are the standard units used.

An absolute pressure of 9 or 11 psia is below atmospheric pressure,
those pressures are said to be a vacuum.

Exhaust from Titanic's reciprocating engines, at a pressure less than
atmospheric, could be directed to the turbine or "bypass" the turbine
and exhaust directly to the condenser. The turbine was used to recover
heat energy from the main engine exhaust which would otherwise have been
wasted, and thereby increase the overall plant efficiency.
