	Hello I try to get saturated steam enthalpy at certain pressure using steam table but there are not all pressure shown in the steam table. How can I do if there is not ptressue and I cannot know enthalpy in the steam table. I can use steam graph but cannot get accurate enthalpy. Is it possible to get the enthalpy using interpolation? I apreciate if someone let me know.

	Yes. Think of it as a graph with a straight line between point (x0,y0) and (x1,y1). If point x is between x0 and x1 then the value y, between y0 and y1, is your answer. https://en.wikipedia.org/wiki/Linear_interpolation

	I've used and recommended this program (WASP) many times for well over 20 years. Very handy, used for under vacuum conditions for distillations.
