Steam_XPS

Calculate the steam quality (vapor fraction) as a function of pressure (P in kPa) and entropy (S in J/(g K)). Use only for wet steam. By default, input arguments and returned values are in SI units. You can change the units of measure, for example, by using the Convert function.

Syntax

Steam_XPS(P, S)

Arguments

• P

  Pressure of the steam. P can range from 0.611212678 to 22064 kPa.

• S

  Specific entropy of the steam. S can range from -0.000155 to 11.921J/(g K).

Returns

Computed steam quality (vapor fraction)

Example

• Steam_XPS(10000, 5)

  [Returns 0.72695]
