Steam_VPT

Calculate the vapor specific volume as a function of pressure (P in kPa) and temperature (T in °C). Use for an entire range from compressed water to superheated steam. You can change the units of measure, for example, by using the Convert function.

Syntax

Steam_VPT(P, T)

Arguments

• P

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

• T

  Temperature of the steam. T can range from 0.0 to 800 °C.

Returns

Computed vapor specific volume in cm3/g.

Example

• Steam_VPT(50000, 500)

  [Returns 3.8894 cm3/g]
