Steam_VPS

Calculate the vapor specific volume as a function of pressure (P in kPa) and entropy (S in J/(g K)). Use for both superheated and wet steam as well as compressed water. 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_VPS(P, S)

Arguments

• P

  Pressure of the steam. P can range from 0.611212678 to 100000 kPa.

• S

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

Returns

Computed vapor specific volume in cm3/g

Example

• Steam_VPS(40000, 6)

  [Returns 8.0055 cm3/g]
