If the cargo oil pump is used for transferring product oil and it's driven by saturated steam. What's the raltion between the capacity of the pump and the consumption of steam?
The raltion (sic) is that the steam turbine has to produce enough power to pump the required quantity of liquid to the required head and overcome the losses.
To achieve this the turbine utilises the energy available in a given mass of steam - enthalpy in minus enthlapy out times the mass flow.
<.....enthalpy in minus enthlapy out times the mass flow.....>
....of the steam, equals the pressure rise times the volumetric flowrate of the liquid divided by the efficiency of the system.

How to answer this?........................Ummm, the more you want to pump, or the more 'head' you need the more steam you will need.
If you are designing these systems, you should know the answer really. If you are on maintenance on a ship or ground placed pump station, The pump volume will be installed, enough to do the job it was designed to do?
If however you want to know more about steam pumps and the volume they can pump with a given head of steam then ask that question.
Take care and no insult intended OK?
