    In the first table how do you get the specific volume (third row) using this steam tables?

    https://www.scribd.com/doc/304835873...Metric-Units-1

    They have the answer as 0.5951 but I don't understand how they got that. Do you have to interpolate? Use equations? I'm so confused.

    Oh, well I can get the moderators to move but by the time do you know how they got 0.595 kg/m^3 in the third row of table 1? Because when I looked for 250 degrees and 400 kPa I wasn't seeing that value. I think I've been looking in the wrong tables cause I been looking in the saturated water and steam but they say its supposed to be superheated?

    Generally people like to see your attempts and then they will try to guide you in the right direction if necessary. Otherwise people think they are doing your homework for you

    I used/looked at the density table and tried to use that value to get v but there's no mass so and its superheated so how did they get v? What are you interpolating? From which superheated table?

    Yeah, I don't know how to get them using this table so I'm confused. It's the one I have to use in exam.

    How did you get that? Using double interpolation?
