The experimental data in steam tables have been measured in laboratories with precision instruments. They have been verified many times throughout the years and are therefore very reliable.
A very simple experience is used to build a steam table. In a closed device, in which a specific flow of water circulates, a known electric current is introduced. From this current, we can infer the exact amount of heat added and we simply record the pressure and temperature at which the system stabilizes.
See the 'Origin of steam tables' related link below for a diagram of this experimental setup.
The steam tables have 16 columns as follows: pressure (absolute), temperature, specific volume of vapor, specific volume of liquid, heat of the liquid, heat of vaporization, total heat of the vapor, entropy of the liquid, entropy of vaporization, entropy of the vapor, internal heat of the liquid, internal heat of vaporization, and internal heat of the vapor (occasionally the external heat of the liquid, vaporization and vapor are included) If the temperature and pressure of steam are known then cross referencing the heat or the volume of a known quantity of the steam can be done. the heat content(enthalpy) of the liquid or vapor can be extrapolated from the chart, as can the entropy and internal energy. The enthalpy less the internal energy = the external energy (or the actual energy required to expand the liquid to a vapor) By determining the starting heat content of steam and final or exhaust heat content of steam the efficiency of a steam engine can be determined. Along with these calculations are the determinations of heat losses, steam quality, loss to entropy,...etc. all calculated using various instruments and the steam tables.
To convert steam usage in tonnes to kWh of gas consumed, you need to consider the energy content of the gas being used. First, determine the heat content of the gas in kWh per tonne. Then, multiply the steam usage in tonnes by the heat content of the gas to get the total energy consumed in kWh. This calculation accounts for the efficiency of the system and provides a direct comparison of energy consumption between the two sources.
Condensed water can be calculated by finding the difference between the enthalpy of steam and water at the given temperature and pressure conditions. This typically involves using steam tables to determine the enthalpy values and then calculating the change in enthalpy to find the amount of condensed water.
Well Vapor And Steam Are The Same Thing,In That Case It Would Be Evaporation Since Vapor/Steam When Liquid Turns Into A Gas :)
Here are some: Steam, Carbon Dioxide , Sulfur Dioxide , Hydrogen Sulfide

The Ohio steam tables are a set of reference tables that provide data on the properties of water and steam at various temperatures and pressures. Engineers use these tables to analyze and design systems that involve the use of steam, such as power plants, HVAC systems, and industrial processes. By referencing the Ohio steam tables, engineers can determine important properties like temperature, pressure, specific volume, and enthalpy of steam, which are crucial for designing efficient and effective steam-based systems.
To be general, steam tables are used to determine the properties of fluid. Mostly used on engine, refrigerator and heat pump. It shows the pressure and temperature require for a fluid to reach a certain amount of energy level.

30 PSIG is about equal to 45 PSIA. Saturation temperature from the steam tables at 45 PSIA is about 274°F. So the steam would be 274°F, or hotter if superheated.

The three types of tables found in Bergey's Manual of Systematic Bacteriology are "General Identification Tables," "Phenotype-Based Identification Tables," and "Genotype-Based Identification Tables." These tables provide information on the characteristics, biochemical properties, and genetic profiles of bacteria for their accurate identification and classification.

Folding banquet tables or any fold tables can usually be found at major hardware supplies stores. For the more elaborate models, specialty shops which can offer customizable options can be found.
