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.

How do you convert steam usage in tonnes to Kwh of gas consumed?
You have to consult tables which give the properties of water and steam (commonly called Steam Tables). You have to calculate the total enthalpy of the steam as delivered, and subtract the enthalpy of the returned condensate (if returned) or of the water as it enters the boiler. In modern steam tables this will be in kilojoules per kilogram. You can multiply by mass to get total energy. To convert to kilowatt-hours, note that 1 kWh = 3.6 MJ. Various organizations have published steam tables in the past. The one published by the International Association for the Properties of Water and Steam is the one to use, particularly the 1997 formulation for industrial application. There are some free caclulators online which claim compliance to the algorithms, but I can't vouch for any of them. It is not straightforward and you may want the services of a competent steam engineer (that leaves me out. I may be able to hack my way through, but I am not "qualified" in this area.)
How do you use thermodynamics steam tables?
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.
What is meant by invertebrates at is - salini I found it in a Malta website for environmental protection. Will it be a place?
is-salini are the salt tables in Malta ^^
Is slate found in common or rare areas?
Slate is found in the pool tables used in most every bar or pub. It's pretty common and easy to find.

What are Steam tables used for?
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.

What anagram is found in tables?
stable
What is the Temp of 30 psi steam?
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.

How much steam pressure would a five inches diameter by twelve inches long with six inches of water in it?
The steam pressure (assuming this is a closed container) will be entirely dependent on the temperature. Look up steam tables to get the pressure of saturated steam at various temperatures.
