Converting Gauge Units to Absolute Units. For SI Units. Steam Pressure [kPa abs] = Steam Pressure [kPaG] + 101.3 kPa. For Imperial Units. Steam Pressure [psi abs] = Steam Pressure [psiG] + 14.7 psi. Important note: Problems can easily occur when absolute pressure is mistaken for gauge pressure (or vice versa), so it is always extremely ...

Take it from me, saturated steam tables are essential to you as a steam user. You’ll make use of these tables to determine the steam temperature from steam pressure, along with its heat energy carrying capability. The data that you read in a saturated steam table refers to steam at a particular pressure, you may also recognise this stage as the boi...
You might think that reading a steam table is a time-consuming and challenging process but it doesn’t have to be this way. My trick is to simply get to know and remember the symbols that make up a steam table. This can help you along the way to reading them with ease: P – Pressure of the system T – Temperature (saturation point) vg – Specific volum...
Gauge pressure is used in steam tables and references measured pressure against the pressure that we would normally experience and will always be zero-referenced on a steam table against atmospheric pressure (1.013 bar). You may also see Absolute Pressure in steam tables, but Absolute Pressure is zero-referenced against a perfect vacuum. To avoid a...
You’ll likely already know that should saturated steam be heated at a constant pressure, its temperature will rise, producing superheated steam. This is because superheated steam’s temperature can vary considerably under the same pressure. For example, at 10 bar g, steam should have a temperature of 184oC. If the temperature was at 200oC you would ...
Example Steam Table. The table columns can be read as: Pressure – the gauge pressure at which the steam table values occur i.e. the pressure at which the experiment to measure the other corresponding values was made. Temperature – the temperature at which the water’s saturation point is reached i.e. the boiling point.

This heat quantity is different for every pressure/temperature combination, as shown in the steam table. 2. Total Heat of Steam (Column 6). The sum of the Heat of the Liquid (Column 4) and Latent Heat (Column 5) in Btu. It is the total heat in steam above 32 F. Specific Volume of Liquid (Column 7).
