Hello, my opinion is that the minimum numbers of gauges on a condensing steam turbine depends what you want to check all what you mentioned are right, but you could add more gauges if it´s inside your budget. IE: lube oil pressure gauges are very important for lube oil system.

Most machines commonly share lube oil system and when you see lube oil inlet pressure or inlet temperature is the same for both machines, but you will see outlet data in local gauges.

What does the steam turbine drives?

If the steam turbine drives a gas compressor or a driven machine that manage a dangerous gas ie: carbon monoxide or a gas containing sulphide, it´s not usefull to put a lot of in-site gauges if not to put sensors and drive signals to the control room because compressor/turbine operators couldn´t go to the machine to see the gauges in those cases you will have to have the machine properly instrumented.

Regards, Mariano.

Is Cp/Cv applicable to steam to calculate?
By: Kent mayhew [2161]

The reason that isobaric Cp heat capacity is greater than isometric Cv is that isobaric involves expansion. Remember our atmosphere has mass, so in order for a system to expand it must displace that mass. And this requires work. So Cp requires work plus the energy to heat the gas , while Cv only requires the energy to heat.

So for all gases and/or steam the work required to expand a given volume is the same that being the work required to displace our atmosphere by a given volume.
