Steam Tables

Dear All,

Hope you all're good, received some queries asking for estimating the steam pressure(absolute / gauge) on temperature basis and Steam temperature on pressure(absolute / gauge) basis.


Recently this query was raised by Mr. Seetha Ramaiah, 

Basically, as per me there wont be any direct formulae to determine the steam pressure and temperature, Since i've tried searching for all those, and haven't received fruitful results, so today i'm posting what i got and what i sticked to regarding this concept,




If you want to know the temperature of steam in the transfer line based on pressure, you can use the below table:

Pressure		Temperature	Water(hf)		Specific enthalphy Evaporation (hfg)		Enthalphy of Steam(hg)		Specific volume
bar	kPa	C	Kcal/Kg	KJ/Kg	Kcal/Kg	KJ/Kg	Kcal/Kg	KJ/Kg	m3/Kg

You can determine Steam Pressure based on Temperature basis, [what i mean is if you want to generate steam at required Temperature the below table can be used],

I hope these tables will be useful to you while performing calculations, and also sometimes on production shop floor also.
