the thermodynamic properties of steam in either English or SI units. Steam Properties, Tables, Phase Diagram and Saturated Steam. (Abstracted from Keenan and Keyes, THERMODYNAMIC PROPERTIES OF STEAM, by permission of John Wiley & Sons, Inc. The two programs steam and thermprop were borrowed from Professor A. If you have a 15-psi steam supply, the tables tell you that you have 945 Btu/lb. Properties of Saturated Ammonia (LiquidVapor): Temperature Table 912. If you know that you need a temperature of 307 degrees F, the table tells you that you need to pressurize the system to 60 psig.
To view these pages in SI metric units, click here. The following measurements are expressed in imperial values.
From any one known value you can determine any of others. Because H 2O can be either liquid or gas at its saturation point, two sets of data are required: data for saturated water (liquid), which is typically marked with an "f" in subscript, and data for saturated steam (gas), which is typically marked using a "g" in subscript.All of the properties of steam are interrelated. This is the point where water (liquid) and steam (gas) can coexist at the same temperature and pressure. The data found in a saturated steam table always refers to steam at a particular saturation point, also known as the boiling point. Newtons Second Law of Motion with the English system of units. Saturated Steam: TEMPERATURE Table STEAM TABLES ( from M. In addition to pressure and temperature, these tables usually include other related values such as specific enthalpy (h) and specific volume (v). 1.17 Given a set of steam tables and sufficient information to indicate the state of the. other units should refer to Chapter 1 and Table III for the appropriate. It's typically used to determine saturated steam temperature from steam pressure, or the opposite: pressure from saturated steam temperature. Table IA provides properties for saturated steam/water. The X Steam Tables are the perfect tool both for replacing paper tables and. This article will introduce steam tables, pointing out the different types and offering an overview of the different elements found within them.Ī saturated steam table is an indispensable tool for any engineer working with steam. XSteam(tSatp,1) returns the saturation temperature at 1 bar. Just as a map (or GPS navigation system) is necessary when driving in a new area or a flight timetable is indispensable when taking the plane, steam tables are essential to steam users in industry.
