How To Read Steam Table How To Find Properties Of Steam From Steam Steam tables based on gauge pressure indicate atmospheric pressure as 0, while steam tables based on absolute pressure indicate it as 101.3 kpa (14.7 psi). also, to distinguish gauge pressure from absolute pressure, a "g" is typically added to the end of the pressure unit, for example kpag or psig. converting gauge units to absolute units. For example if the dryness fraction is 0.8 for steam at 9 bars absolute pressure in bars. referring to the steam table above, hf = 743 kj kg, l = 2031 kj kg, h = 743 0.8 x 2031 = 2367.8 kj kg. this is a simple sample calculation; for more complex ones, please refer to your book on thermodynamics, but the essence is the same. These other properties are usually obtained utilizingeither the mollier diagram (if the substance is steam) or the saturated and superheated steam tables,as shown in the figures a 1 and a 2. the following two examples illustrate the useof the mollier diagram and the steam tables. example 1: use of mollier chart. C) since state (1) is specified as saturated liquid at 200 kpa, we use the saturated pressure steam tables to determine that t 1 = t sat@200kpa = 120.2°c. d) from the t v diagram we determine that state (2) is in the superheated region, thus we use the superheated steam tables to determine that v 2 v 200kpa,300°c. thus v 2 (658 liters). e.
