Steam_SPT

Calculate the vapor specific entropy as a function of pressure (P in kPa) and temperature (T in °C). Use for an entire range from compressed water to superheated 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_SPT(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 entropy in J/(g K).

Example

• Steam_SPT(40000, 600)

  [Returns 6.017 J/(g K)]
