Using linear interpolation, estimate the specific volume of water under the following conditions using data from the steam tables: (a) P = 1.9 MPa ; T = 250 C (b) P = 1.9 MPa ; T = 300 C (c) P = 1.9 MPa ; T = 270 C Look up the specific volumes of water that correspond to cases (a), (b), and (c) using the steam table. Comment on the agreement between the two sources.
