If you have a pump with 260KW absorbed power at pump shaft and you want to run it on steam turbine then the steam consumption will be based on aborbed power by pump shaft or the steam turbine power?

Answer 1

Pump power is based on

BHP = Hydraulic horse power + pump mechanical efficiency

Absorbed power = BHP + electric motor eficiency

in your case you dont need to account for power absorbed by pump shaft as it would include motor efficiency.

your steam consumption will be based on following :

normal operating = based on BHP of pump

Maximum required = turbine rated power
