Question:

For H2O, plot how the specific volume (v), varies with T in the superheated vapor region for a pressure of
(a) 10 kPa.
(b) 50 kPa.
(c) 10 MPa. Take at least 10 points from the saturation temperature to 600oC. To reduce the data into a simple correlation, plot pv against T.
(d) Explain the behavior of the reduced data.
