Specific Steam Consumption | Advanced Steam Traction
Specific Steam Consumption is defined as the steam consumed by a locomotive’s cylinders per unit output of power. It is typically measured in kg/kWh or kg/KJ. A locomotive’s Specific Steam Consumption carries important implications as may be deduced from one of Porta’s favourite equations: Thus for any given boiler output, a locomotive’s power can be increased by reducing its specific steam …

Steam Heating Process - Load Calculating
Increasing steam pressure increases temperature - and increases heat transfer. Heat up time is decreased. Overall steam consumption may increase - due to higher heat loss, or decrease - due to to shorter heat up time, depending on the configuration of the actual system. Flow or Continuous Heating Processes

Specific fuel consumption | Article about specific fuel
The ratio of the fuel mass flow of an aircraft engine to its output power, in specified units. Specific fuel consumption (abbreviated sfc or SFC) is a widely used measure of atmospheric engine performance. For reciprocating engines it is usually given in U.S. Customary units of pound-mass per hour per horsepower [ (lbm/h)/hp or lbm/ (hp·h)], and International System (SI) units of kilograms per hour per …

How much steam is required to generate 1MW of electricity
This is called Specific Steam Consumption (SSC). Efficient machines are having Low Specific steam consumption i.e, to generate 1 MWhr they consume less steam, which is always preferable. Mostly with the size of the turbine it is reduce. Our 156 MW Steam turbine use to have SSC of around 0.37 mw/tn. Near about 2.7 Tons per MW generation.

Wet Steam vs. Dry Steam: The Importance of the Steam
Steam tables contain values such as enthalpy (h), specific volume (ν), entropy (s), etc. for saturated steam (100% dry) and for saturated water (0% dryness), but typically not for wet steam. These can be calculated by simply considering the ratio of steam to water, as described in the equations below: Specific Volume (ν) of Wet Steam

Specific volume - Wikipedia
In thermodynamics, the specific volume of a substance is the ratio of the substance's volume to its mass. It is the reciprocal of density and an intrinsic property of matter as well. Specific volume is defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the cubic meter per kilogram (/). = = −

What is Steam? | Spirax Sarco
The extract from the steam tables shown in Table 2.2.2 shows specific volume, and other data related to saturated steam. At 7 bar g, the saturation temperature of water is 170 °C. More heat energy is required to raise its temperature to saturation point at 7 bar g than would be needed if the water were at atmospheric pressure.
