STEAM'92 v3.2

This new release has greatly enhanced consistency especially 
near the critical point.  This is very region to resolve and 
much work was required.  Transport properties in the two-phase 
region are also accelerated.  Also, the copy facility has been 
improved (F1/F2).

                     NOTES

Natural Convection Heat Transfer Coefficient
	This term is a portion of the nondimensional Grashof 
	Number used for free convection heat transfer studies. 
	The full term is:

		Gr = BETAnc * ( L**3 ) * ( T - Tinf )

	where
		BETAnc = the term provided by STEAM'92
		     L = the dimensional length
		     T = the local fluid or body surface temperature
		  Tinf = the ambient fluid temperature

	These terms are dimensioned such that Gr is nondimensional.
	Where T - Tinf is large, it is recommended that this term
	(as well as the Nusselt number) be evaluated at (T+Tinf)/2.

Units Coefficient
	Some of the units have coefficients, or exponents with the units
	name. This is intended to be read as a literal suffix to the
	number showing in the cell: don't invert the sign, just assume
	that it is a multiplier to the number showing.

Speed
	If you do not have an 80i87, we recommend MicroWay or Haupage
	as sources. They focus on 80i87 support and have treated us
	well. 

	Please let us know if you have any problems running 
	the program on your system.

Cv and Alpha:
The current release has incorporated new solvers for Cv and alpha 
(isentropic compressibility), in the 2-phase region.  These solvers 
circumnavigate the calculational problems as well as accurate results.

"Gamma"  Becomes  Isentropic Exponent:
To make it more useful, "gamma" is now the isentropic exponent and calculated explicitly according to

        gamma = -(v/P)(dP/dv)|s

which is commonly used where approximations of the perfect gas
relations are useful. 

"Z" Becomes Choked Mass Flux:
The critical mass flux, W*/A, was substituted for the Z coefficient.
W* is evaluated by looking at the input state values as TOTAL conditions.
Speed of Sound:
The sonic speed is now calculated explicitly using the isentropic compressibility in the two phase region.

Benchmarking for the new data:
All of these resulting values and conventions are additionally 
consistent with the ASME Steam Tables, 5th Edition.
