Steam_SPTL

Calculate the liquid specific entropy as a function of pressure (P in kPa) and temperature (T in °C). Only use for compressed water. For any T higher than the saturation temperature for P, the function returns an out-of-range error. The function accepts any T in the temperature range as long as P is greater than the critical pressure. 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_SPTL(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 liquid specific entropy in J/(g K).

Example

• Steam_SPTL(30000, 500)

  [Returns 5.7956 J/(g K)]
