3.7 The following table lists temperatures and specific volumes of water vapor at two pressures: p = 1.0 MPa T (C) 200 240 280 p = 1.5 MPa v(m/kg) T (C) v(m/kg) 0.2060 200 0.1325 0.2275 240 0.1483 0.2480 280 0.1627 Data encountered in solving problems often do not fall exactly on the grid of values provided by property tables, and linear interpolation between adjacent table entries becomes necessary. Using the data provided here, estimate = (a) the specific volume at T = 240C, p 1.25 MPa, in m/kg. (b) the temperature at p = 1.5 MPa, v = 0.1555 m/kg, inC. m/kg. (c) the specific volume at T = 220C, p = 1.4 MPa, in m
